‘Five Eyes’ Nations Quietly Demand Government Access to Encrypted Data

My impression from the previous crypto wars and the skirmishes that have followed is, as technologists, we take a very tactical view of technology, and underestimate the intentions of people who understand power and politics the way we understand information systems.
The way we see the security of a system, they see the sovereignty of a state. Just as incompleteness in our code can yield system level compromises, incompleteness in their ability to apply their rules to their territories and domains also yields compromises that makes the whole system untrustworthy.
I don't agree with what I perceive as their Hobbes-ean need for total control, where I think the localized, depth first absolute authority of a state becomes malignant when it is applied breadth first and in totality to all aspects of life, but you can sympathize with the urge without agreeing with it.
They should be mindful that post-Snowden, no matter how large the field we live in, people have seen the walls and bars at the perimeter, and that broad perception is likely a greater source of instability than any gaps in the ability of the state to enforce them.
Viewed this way, the 5Eyes statement seems unwise.
They want to decrypt data because they want to protect people from threats. I'm not saying we should allow them to, but ascribing malintent is misguided.
Edit:
Before the reflexive downvotes ask yourself: Who is asking for the ability to decrypt? These people are making half or less what they could make in the private sector.
If they actually get the information then the next attack will make them look worse.
I suspect you're correct. However, the systems we design must be strong enough to deal with the inevitable lone wolf or corrupt regime. If we rely on average people with good intentions being the only people in power we will fall to the first outlier to show up. This isn't a matter of pessimism or distrust. It's a matter of us having to be successful at defending every attack, every time and them only having to succeed once. All it takes is one. You design the system not for the authorities you hope to have in power but for the one's you fear having power.
Governments have many tools, the most powerful of which is physical coercion, to gain access to data they have reason to believe exists. I want the serving and execution of a warrant to be expensive (and legible, except in the most rare, unique - and thus highly regulated - circumstances). If it is expensive then it will have to be targeted - resources aren't infinite. Making these powers trivially cheap and unnoticeable when exercised will only lead to widespread abuse and unwarranted violations of privacy as we have seen time and again whenever dragnet surveillance becomes cheap, easy and accepted in a population.
Nation States already have the power to inject silent updates and "hack" foreign agents -- everything they're asking for under these new laws. They generally do not need to break encryption or gain encryption back doors. They do full take on the data before and after it is encrypted and decrypted. This, for the most part, is expensive and thus targeted, for sophisticated intelligence targets. Governments now want to expand this power which has been traditionally reserved for targets which pose grave national security risks. Governments want to apply a military tool to civilian police investigations - effectively militarising police surveillance of all citizens. Are sufficient effective checks and balances even possible for such a powerful capability?
Add to that, the fact that governments want us to pay to create and maintain this surveillance directly, thus hiding the true cost and scope of their investigatory activities - and a means by which we can challenge the implementation of such a system lawfully, by compelling all private companies to build in vulnerabilities on demand. Worse, once those vulnerabilities are in place in a system, all users of that system are vulnerable, not just the targets of an investigation - in effect, making all users, except for just the first one on that platform, cheap and easy targets. Eventually, this facility will be built into every system at design time - it's just another regulatory requirement; and even that barrier, the first target, will be gone.
The fact that they want to use these extremely powerful, hard to detect tools and techniques, developed for covert surveillance against foreign powers who pose a national security risk, against us common citizens should be concerning. The fact that they are attempting to push the burden of creating these tools onto the public, the public against which they will be used, and in so doing, make exercising this power extremely cheap and - beyond the first target on a platform, anywhere - effectively free should be downright terrifying.
Again, it's not about malintent; it's about protecting from the outliers - the abusers - because, while the abuse of a single individual or community can be extremely harmful to that individual or community, widespread abuse of such an investigatory tool is almost entirely impossible to fight. These tools defeat the very means by which people organise resistance against oppression: free, open and private communications.
We should think very carefully lest we put a surveillance ratchet in place that will become very hard to coordinate against by its very nature if abused. Given the history of "exigent powers" becoming normalised introducing such a system seems extremely dangerous.
I completely agree; and I assure you I do not think that I have all the answers or have considered every angle, but I do think about this line of thinking quite frequently and I just don't know how to square it.
On the one hand, I think we need intelligence to stop a cyber 9/11 (or worse, a cyber Hiroshima or holocaust), but on the other hand you're completely right that the outliers are going to show up. I don't know man. It's a tough one.
I tend to favour prioritizing the character of the people that get into those positions and making our political systems as robust as possible, but that's just a stab in the dark. What you've outlined is a real problem that I don't know how to solve.
This is not true at all. That is the smoke screen they have put up, but the real intent is to institute pervasive surveillance and have more power over people. They're lazy and have decided that defeating encryption is the easiest way to bypass the effort required to investigate crimes properly.
Attributing this policy drive to altruism is truly naive wishful thinking.
And attributing it to malice is truly naive pessimistic thinking.
The reality is that both of those positions exist. There are people in government (and anywhere) that want to help or hurt people. I find transparency more helpful than hurtful, because we are in an age where there are public repercussions for visible actions.
There are hundreds of thousands of people with top secret clearance for fucks sake. They're not all part of some conniving cabal.
The output of the machine is what matters. If the output of the machine is bad, then everybody that is a part of it is and unwitting bad actor.
We have to make sure we don't make bad public policy machines.
Rights and justice are based upon the same assumptions - no you can't take the prosecution's word that they are totally guilty because they look shifty and aren't from around here! They have to prove that there was a crime and that they committed it beyond a reasonable doubt.
Until they can prove say secure communication in itself can kill anyone in the world like a magic spell they have no case for this.
Pessimism is thus wise in the same sense that you shouldn't ask a stranger on the street to hold your wallet for half an hour.
My government is literally killing refugees in order to make a public statement that seeking asylum in our country is worse than staying in a country where you face death from bombs, lynch mobs or government execution.
I think my interpretation of this Five Eyes directive as a lazy power grab is being extremely kind to the people involved because I'm implying they have a plan and are aware of what they are doing.
And, of course, once the group has managed to squash the voices of it's individual members it is open to exploitation by external forces, like money from lobbies (designed to sway the group) or bribes to individuals (often in order to get the few who disagree to align with the group).
Some of the people in government and law enforcement want to decrypt data to protect people from threats. Some of these groups are looking at their authority and seeing it erode, they are looking to decrypt data to preserve that authority. As we have seen in practice, others are looking to extend their authority (as in the case of projects like Echelon, etc.) by having real-time access to people's data.
While you might be able to agree with some of these people some of the time, I strongly doubt you can agree with all of them all of the time. And if you find that you cannot agree with all of them all of the time then, in my opinion, they probably should not have the ability to decrypt any of your data.
I think we all would do well to remember that while government and authority love to talk about pornography, child abduction and terrorism the vast majority of people have nothing of the sort on their phones or computers. Protecting the data that everyone has should not be forgotten (financial, private, corporate, etc.)
>Of all tyrannies, a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end, for they do so with the approval of their consciences.
-- C. S. Lewis
While I agree with your general point about not ascribing malign intent (at the very least, the misunderstanding about the security implications of weakening decryption seems primarily a case of Hanlon's Razor to me), but the "making half or less what they could make isn't convincing to me. There are those who'd happily sacrifice raw dollars for the power of being able to decrypt
There's always abuse. And since their activities are secret, well...
True, but those directing and financing them are. Sorry but this is exactly how being in power works. You don't spy on common people because you want to arrest them all now, but rather to keep an advantage position "just in case". Power is all about maintaining an advantage position with respect to an adversary or a potential one. Should you one day, say 10 years from now, become a political figure, the pictures someone collected 5 years ago of you dancing naked and stoned in a disco would instantly become a tool to be used to either destroy your political career, or use it for their gain through blackmailing. Knowledge is power. AI training aside, gathering all possible information about everyone is how Cardinal de Richelieu would get something enough to hang any of the 7 billions people living on this planet, or have them work for him 24/7.
Many of these people are willing to take a lower salary to help others but history has shown that many, many others take lower paying jobs in government because it affords them power over other people.
This may be true, but even if so it is irrelevant. You do not need evil intentions from hundreds of thousands of worker bees to make something ugly. Just a few politicians or leaders on top are sufficient. I suspect in WW2 Germany most factory workers making gas chamber equipment were diligent, hard working, family loving fellows who did not know the full use for the product they were building.
And yes, I do not trust politicians who lie to the public "for its own good". I think most of those are in it for the power.
In terms of lying to the public: I agree to a point. I think there are certain truths that can't be voiced for fear of enabling our adversaries. That being said, however, I think it was counter productive for our intelligence agencies to lie about the dragnet. It almost invited a Snowden like character and the inevitable public blowback wasn't worth it.
People who are known for running the largest spying operation known to man, with utter disregard for privacy. People who oversaw dark sites? You tell me.
> these people are making half or less what they could make in the private sector
But they couldn't get the same level of access, they couldn't see what their ex is doing, for example.
The only evidence is a lack of evidence. There are documented examples that surface on a rare basis.
The fact something has a term has no impact on the frequency of the event. Unless you think that a Dyson Sphere is something that's been observed.
That's "in it for the power".
Power doesn't look the same from the inside. Basically nobody (except college-age Mark Zuckerburg) goes around saying "I'm an evil Machiavellian genius that's going to fuck over the world for my personal benefit." Instead, the feeling of having power, from the inside, is the feeling of being able to make decisions for other people for their own good. It's the ability to deal with people as abstractions who should want things, whether they actually do or not. People can't be trusted to invest their own money, so we need regulations so that only the wealthy can invest. People don't know what they're searching for, so we need to correct their queries for them. People want lower prices, so we'll give it to them by turning the screws on our suppliers. People would collapse into chaos without law and order, so we enforce it.
Sometimes the powerful are even right in their views - after all, very often that's how they got to be in power in the first place. But that doesn't stop them from being resented, because the resentment stems from the fact that they are making decisions for other people that those other people neither consent to nor really want. Someone who is actually "not in it for the power" is someone who says "I trust you to live your own life how you want, as long as it doesn't prevent me from living how I want."
Could be, but you're making a VERY dangerous assumption about their lack of gullibility.
Technology is a difficult field to understand - just look at all the asinine content filtering proposals to get a feel just how out of their depth well-meaning politicians can be. Now think about encryption, an inherently much more difficult subject. The same, or similarly well-intentioned, politicians are going to be completely out of their depth. They can be goaded, led and nudged towards a goal they do not, and indeed can not understand.
Make no mistake. This proposal and its talking points are being fed to the talking heads by parties who want to outlaw end-to-end encryption.
The politicians talking about this are probably innocent of malice, but they sure as hell are guilty of heinous ignorance.
I looked into contracting in the UK for a national agency a couple of years back. The day-rates they proffering were almost double a London day-rate (before negotiation; I can only imagine what could have been secured). There's a deeply invasive interview process but they would cheerfully pay outrageous amounts to secure talent (and I wasn't even particularly good!). I assume not many people have the skill-set they're after and even fewer pass the checks. Perhaps it's different in the US but that was very much the state of affairs in the UK circa 2015
If you asked them many would say that a state must maintain total control within its territory or someone else will fill whatever vacuum remains -- the mafia, other states or their intelligence agencies, private cartels, etc. Once such agencies get a toehold they can grow their power and eventually challenge the dominant structure. In many cases the new boss may be worse than the old boss.
Politics is all about compromises. Police and intelligence agencies always sound like they are asking for total Orwellian control because they know they'll get only 1% of what they ask for -- so ask big. It's a negotiating strategy.
they have a level of surveillance that orwell could not have imagined. orwell imagined hidden microphones and highly visible cameras. we have all of those things and far more.
you see, if they negotiate 10000 times and they get 1% of what they want each of those times, things move in their direction and eventually they have more than what they originally wanted.
With mass surveillance I get the idea they know they get 99% of what they ask for, and even more, they mock us because they know they can circumvent the remaining 1% easily through parallel construction.
Remember those NSA slides where they mock the public for willingly buying smartphones that can be tracked everywhere? Yeah, we're the morons, not them who openly lie to the public and redefine language itself to make what they're doing not a crime against humanity.
It's as if they installed cameras on every street and mock people for driving, except of course, that too is now practically normalized under the guise of "safety".
That doesn't make it right.

It isn't spying if they willingly exchange the information they have intercepted. Straight from the link you posted:
Yet there have been reports in the British press — amplified most recently by former NSA contractor and leaker Edward Snowden — that that’s not the case, that the Five Eyes spy on one another’s citizens and share the information to get around laws preventing agencies from spying on their own citizens.
I trust the BRUSA documents over the word of a high school dropout who failed his analyst exam for misunderstanding the course materials and misdescribed PRISM for misunderstanding the documents he leaked.
For those who remember, this is the program with the famous "smiley face" drawing of where Google decrypted data at their network edge.
You misunderstood Snowden's documents. The UK tapped undersea cables entering their country. They did not break into Google's datacenters. According to Snowden's documents, the NSA is not allowed to collect and store US citizen data, no matter the source. There was at one time email metadata collection (from/to/when) from that source that was ended prior to Snowden's leaks according to his documents.
https://www.washingtonpost.com/world/national-security/nsa-i...
Refer to the primary documents when you see articles like the one you posted with contradictory information like "full take" vs. "100,000 selectors" with a mere "millions of records every day."
The article you posted is not about MUSCULAR. MUSCULAR did not require FISA authorization; that was kind of the point of structuring it the way they did.
My article is about a data collection program that used MUSCULAR as a source.
I'm done with this conversation; it's clear you're not acting in good faith.
I pointed out that the article you posted said the exact opposite of what you claimed it said (in addition to saying what you claimed it said). How is that not acting in good faith? If the article is contradictory, you need to go to the primary documents, which were available from The Guardian.
Encryption was specifically created to guarantee the integrity of an A->B interaction. If we're compelled to break that, then the whole system is no longer able to be trusted and its integrity is shot.
Isn't this why spies always meet in person and go to great lengths to set up dead drops etc.
Edit: Just now realizing that you meant we shouldn't trust encryption and phones, not our home. Whoops. Leaving my response for posterity and lulz.
Spies meet in person because they're people of interest. They take the job knowing that nothing they do is ever really done in secret.
But from a professional, and WWII hero:
> 17. The greatest material curse to the profession, despite all its advantages, is undoubtedly the telephone. It is a constant source of temptation to slackness. And even if you do not use it carelessly yourself, the other fellow, very often will, so in any case, warn him. Always act on the principle that every conversation is listened to, that a call may always give the enemy a line. Naturally, always unplug during confidential conversations. Even better is it to have no phone in your room, or else have it in a box or cupboard.

There are things handset makers could do that would allow law enforcement access to a device without compromising the security of every person using that device. For example, they could add a connector to the logic board that grants access to the keys after a fuse is blown. It would only work on devices that law enforcement have in their possession and once they blow the fuse, the device is otherwise useless so you don't have to worry about using a device that's been compromised. It could even be designed so that the extracted key is encrypted and can only be decrypted by Apple after they receive physical possession of the phone and a court order.
A scheme like this would individual phones that law enforcement have in their possession to be accessed. It wouldn't allow mass decryption and so normal users are still protected. That seems like a reasonable compromise to me.
At least with key escrow we could laughably pretend that the government would keep their master keys secure. You are suggesting that all portable devices ship with security that can be defeated with a screw driver and hoping nefarious people don't react by installing actual security in software.
Only if they could also secure Apple's cooperation. That's what I was addressing when I said "the extracted key is encrypted and can only be decrypted by Apple".
Once apple has the keys to the kingdom what is stopping the government making apple give the government such keys ensuring that no warrant is required.
What is stopping users from using software that is ACTUALLY secure.
The same thing that's stopping them from silently requiring Apple to include backdoors into every device today.
> What is stopping users from using software that is ACTUALLY secure.
It's the same as with a regular phone line. Users are free to speak in code or use an analog scrambler. Just because a particular interception technique isn't perfect doesn't mean it wouldn't be valuable to law enforcement.
There are practical differences, sure, but it’s all the same principle.
It’s not just phones or computers, either — The UK was well known for having high CCTV density well before the proliferation of low-cost digital cameras; By my estimate is now well within government spending limits to put all movement under surveillance by putting cameras on every corner which combine ANPR and facial recognition to cover pedestrians and cyclists as well as motorists; and laser diodes are so cheap every window, never mind person, can be surveilled with laser microscopes.
This is also cheap enough for criminals to do it. I recently got (fake) scam blackmail emails demanding bitcoin under the threat that they had used my webcam to record me watching porn (duct tape over my webcam says they didn’t), but imagine a local crime gang doing that with a drone pointing at your window.
We have to change a lot of stuff in out society very quickly to keep us all safe. We need a world where none of us need secrets, because very soon we won’t have the ability to keep them. We also need the ability to survive ourselves breaking the law, because the law was created with the (at the time reasonable) belief that only important violations would be brought to the attention of the authorities, because most of us can’t get through the day without violating several [1], and because even though current state-of-the-art A.I. can’t automatically enforce all those laws, we should assume that is coming.
But not just what, also how fast it changes and how slow we react: How long ago was it demonstrated that keys can be duplicated from a single image taken by a telephoto lens? And how many keys have been made safe against it since? The only thing keeping us safe is that even the bad actors aren’t keeping up with the tech. That isn’t good, because it means that whoever does use it will look, what’s the phrase, “indistinguishable from magic”.
That's a maybe. You are however vastly overestimating the time it would take for the UK government to go to tender over such a platform. Then you are overestimating by an order of magnitude the private sectors ability to deliver such a platform within a reasonable budget and within the next few decades.
Have you looked at government infrastructure projects? Thankfully they set a reassuringly pitiful benchmark.
For now..
I agree with the rest of your comment wholeheartedly.
Of course, if the government was competent then we wouldn’t have this problem in the first place…
You assume that they work with the same enthusiasm on the projects we benefit and on the projects they benefit.
Most interestingly are the justifications for these things. Widespread ANPR means it's easy to find people who are driving their cars without MOT, VED and insurance. People without those are liabilities to us all, so we don't want them on the road, right?
It's just a happy coincidence that the security services also get to monitor more and more movement in the country.
I wish they'd fund health and social care with as much enthusiasm.
Us technologists should know how much this stuff matters from the huge effect good design has on product adoption. (Or dark patterns on user behaviour). This is the same effect in action - changing defaults changes the behaviour of the majority.
Another example: People say that “if you make guns illegal only criminals will have guns”. Yet here in Australia very few crimes are committed using firearms. This is the same effect in action. (I’m not arguing for gun control - just that these laws have an effect)
And with that in mind, I think the reason why we’re finally seeing a big push from the 5 eyes is because finally, finally one of the big chat platforms (WhatsApp) has rolled out end to end encryption. That lowered the bar far enough that privacy from the government is becoming the default.
One implication of this way of thinking is that it changes where the battle lines are. To win, the government doesn’t need to make end to end encryption impossible. They just need to make end to end encryption a bit difficult and non-obvious. Doing that will probably push the % of criminals who use proper encryption back into single digit percentages. After all, if you can research and understand the implications of application and messaging security, you can probably make a better living working at an IT desk somewhere than you can from stealing cars. Law enforcement would probably see that as a huge win, even if all us techies can keep sideloading Signal or whatever.
Personally I don’t consider that good enough - I want a society where everyone has privacy. Not just those who have opted in to it.
From your last paragraph, I think we basically agree.
I doubt that. I think the main thing keeping cars safe from the 1% or so who don’t care about the law or ethics of theft is that it’s almost impossible to get away with it. Those with the relevant skill and the willingness to be criminals probably just take an easier approach, like card skimming.
This belief is based on how much second hand cars are worth and therefore how few cars a thief would need to steal each month for a very big salary.
Likewise if they ban end-to-end encrypted chat apps from the app stores, I bet that would decimate the number of people who used them. Even if anyone could just get an android phone and sideload signal, in practice adoption would still fall low enough to make law enforcement happy. Even amongst criminals.
I know we're already talking about the law, and there are always ways around this, but you're probably better off sticking a foreign plate on the car.
I find this type of thing the easiest place to purchase number plates because they don't make you jump through a load of hoops with sending copies of the V5.
UK statute is painful to read and interpret though. I may have missed something.
The context of this comment seems to imply these have something to do with the state?
Regardless of who owns the ANPR, since their sole purpose (if you ignore the survelience aspect) is cutting down crime, the data will end up with the state eventually.

The problem is not so much the _initial_ justification. It's the inevitable "control creep" [1]. When something bad happens, they'll just go "hey we have this vast surveillance network in place, why don't we just re-use it for XYZ". That is the fundamental reason why people need to be so vigilant and militant against mass surveillance. Whatever the initial justification was for putting it in place is irrelevant in the long term.
[1] Control creep is where the data generated for one form of governance is appropriated for another
I can't see how the DVLA could alone justify plonking £10k in hardware, £30k in installation alongside a little rural road in the middle of Norfolk.
Ah crap, I'm running out of excuses.
And doesn't even work, people use fake number plates.
Must match make model and color with the number plate, also must make sure that the real number plate isn't used ~simultaneously somewhere distant.
takes plate from car
FTFY
And do what, dispatch the police immediately to both plates? It's also a question of not be caught _for how long_
Of course the story would be slightly more believable if not for the fact that shortly after I read it, the police sent me a speeding ticket for a car which I had sold nine months earlier.
"I wish they'd fund health" How do you know they're state funded cameras?
Just a happy coincidence that a large portion of my job is interfacing booking systems with ANPR installations. The ones down the road are MAV cameras. Not cheap.
Yeah, they might be using them as CCTV. But that's a lot of wasted money.
>It's just a happy coincidence that the security services also get to monitor more and more movement in the country.
Automated and near-perfect enforcement of minor civil infractions sounds pretty damn Orwellian to me.
I think you've got the scope creep backwards. They get all these systems in place by screaming about security and terrorists then say "well since the system is already here let's use it to keep our citizens on a tighter leash". Then they justify it vilifying these people who commit minor civil infractions as criminals when in reality they're your neighbors.
My point is you don't even need to wheel out terrorism every time to get this stuff through comfortably. You can just play the social injustice card.
[1]: I've completely forgotten the name of it. I've read a few studies on this and they're just amazing how strongly people feel about people unfairly getting one over on them. If anybody reading this knows the name of what I'm talking about, I'd appreciate a reply to remind me.
… which is impossible? This would require that the government never gets corrupt because you need secrets to get rid of a corrupt government.
…
At least, that’s the good outcome.
It's a function of popular acceptance (or at least acquiescence) which can acheived by any combination of perceived rectitude or overwhelmingly capacity (in practice, it's usually a blend of the two, and not just one or the other, in any stable state.)
This is arguably the biggest problem of all. Selective enforcement is already a thing, and is only going to become a bigger problem. Just look at all the bullshit prosecutions that have happened in the UK over things said and done on social media.
Police are also increasingly keen on downloading the entire contents of people's smartphones (and prosecuting you if you don't give up the password). So anyone who comes to the attention of the police is at risk of having their entire life pored over to look for any other infringements.
Maybe Apple could fork the iPhone line with devices that retained nothing locally. That ran entirely in RAM, working with minimal data from iCloud. And which fully wiped RAM whenever not in active use. Basically like Tails.
Fixing the issues you list, are part of regaining trust in the political system overall. If it doesn’t get fixed slowly and methodically thing will just get worse and worse until something snaps.
Because the former, I absolutely agree with you. I’m imagining the latter.
What they want is to be able to wiretap people, without them knowing. Because if encryption is what's bothering them, you can get a warrant, seize the phone and/or computer, and make the owner unlock it / give you the keys, by law.
It is perfectly logical and lawful. However, if unwarranted (in the sense of without a warrant) wiretapping is involved, then yes, encryption "hinders the law enforcement". Except it doesn't. Because as mentioned earlier, just get a warrant, and make the owner unlock / give you the key, by law.
It doesn't hinder the law enforcement, it hinders the intelligence agencies work and makes it less invisible. And I kind of think that's a good thing too.
That only works if you can threaten to put the owner into jail for not complying. If you're trying to spy on communication between two people outside your jurisdiction, you're out of luck.
(that doesn't mean I support the US governments attempt to undermine secure communication)
Somehow, an attacker can have your whole conversation log (encrypted), including the key exchange, and be unable to retrieve the key used, even if he has the credentials you used at the time the key was generated.
The real crux of the question may be, "How does Diffie-Hellman work?" (Well known key exchange method.)
I don't think somebody living outside of UK cares. The threat only wors if that person lives in UK jurisdiction. Not everybody does.
Theoretically, let's say you use VeraCrypt or something similar to create a password-protected volume inside a big .mp4 file using steganographic techniques. A second secret password is set, which can decrypt another hidden volume which contains the actual sensitive data.
You give out the password for the first volume under duress.
Would that be enough to satisfy the law? If so, isn't it undermined?
Once again, this is in context of UK law. So speculation about rubber hoses in dungeons isn't particularly relevant (luckily).
> Ordinary Americans — including President Trump’s former lawyer, Michael D. Cohen — are also increasingly using encrypted apps to conduct delicate conversations to prevent monitoring by the government or others.
"Ordinary Americans" are not only using "encrypted apps" to conduct "delicate conversations." People, regardless of jurisdiction, are using these applications because they expect that their private conversations are and will remain private -- especially in a world where digital interactions are replacing/will continue to replace face-to-face interactions.
If I have a conversation with someone over coffee at my kitchen table, I wouldn't (necessarily) consider that conversation to be "delicate." Regardless, I wouldn't want any person or government entity to be able to listen in -- surveillance inhibits freedom of expression and the results are often without context.
Not just a good thing but isn't it really the point of the whole exercise?
The 1946 USUK act that officially created the five-eyes in the first place post-Atlantic treaty needs to be completely re-evaluated and potentially scrapped.
Obviously, the Five Eyes don't see it that way. But I gotta wonder how commonly Tor is used among TLAs, and how the debate goes, if it is. Because this would destroy Tor. Unless operators were totally anonymous, and relays only stayed up until targeted.
And actually, your comment makes no sense. Controlling exits shows where traffic goes. Exits don't connect directly with users, but rather through middle relays, and either entry guards or bridges. So adversaries either need data from all three relays in circuits, or they must control both ends, and be able to signal through circuits. That's how CMU researchers pwned users and .onion sites, using the relay-early bug, which allowed intra-circuit signaling.
That being said, what they're referring to is pretty old research and I haven't heard about any evidence proving any agency controls a large amount of the network.
For a more current account of modern attack methods against Tor this paper[1] is a pretty recent compilation of researched attacks. The Tor developers actively try to defend against these but you should still be careful, it isn't researched enough yet (read: Tor isn't that old) to defend against resource rich attackers.
It's a great review. But I've read much of the covered literature. And I'm not aware of anything published which shows traffic analysis being effective in practice. On the actual Tor network. If there is, I'd love to see it.
Also, as I've said, it's dangerous to rely solely on Tor. It's trivial to identify all Tor users, from ISP data. And with a honeypot website or .onion site, an adversary can modulate to help with traffic analysis. But if users are hitting Tor through nested VPN chains, the universe of traffic to analyze becomes much larger. And so false positives interfere with correlation.
As far as alternatives go, maybe they have something like Tor (onion routing) or I2P (mix networking) that user covert channels. It could even be running on government-controlled Tor relays. Or maybe installed as hidden malware.
That seems unlikely, of course. But remember when allegations about ENIGMA were totally conspiracy theory.
I will say (while acknowledging that I can't prove this) that I have friends who work in national defense and law enforcement, for whom Tor is an impediment. I've never heard them talk about a magic decrypt button; quite the opposite. So if Tor can be decrypted, it is a capability that is closely held and rarely used.
It's not that there's a "magic decrypt button" for Tor. However, it's very likely that the NSA and GHCQ, at least, have some capability to identify Tor .onion sites and users. But they arguably don't want to reveal capabilities, and so are very careful about disclosing information. To some extent, that happens under programs like the DEA's SOPA. But on the other hand, recall that the NSA was cagey about revealing intercepts that could have prevented the 9/11 attacks. Or that charges against the Weathermen were dropped in 1973, after the (then unnamed) NSA got squirrelly about its intercepts being introduced as evidence.
Overall, I'm relatively confident that Tor isn't fundamentally backdoored. But there's no way to know what's going on with any .onion sites that you access. They could be FBI honeypots. Or Russian honeypots. Or independent criminal honeypots. You gotta treat them all as radioactive. As sources of malware and worse. That means at least using Whonix, running on a Linux host machine. And better yet, a dedicated host, used only for Tor and other iffy stuff.
It's dangerous to scare people away from tor on the basis that it might have vulnerabilities, because anything else is certainly worse.
I2P has far fewer users, but every user is a router by default. Tor users have to opt-in to be a relay.

That's kind of the system we have for everything else that isn't digital communication. I don't support backdooring but this line of argument, in itself, is not likely going to convince policymakers.
But good luck convincing policymakers to be beholden to such plebian concerns. Does nobody remember any time that such blanket surveillance was abused?
Edit: Also, it's arguably moral to violate obviously unjust laws. I mean, that's how the US was founded.
Still, a more-or-less lawless Internet is arguably distinguishable from lawless society overall.
Edit: Also, my perspective is colored by living with the War on Drugs for some decades. Having friends spend time in prison. Helping support others to avoid prison. Reading about millions more imprisoned, predominantly minorities. So I'm rather cynical about "society of laws".
And some years ago, at perhaps the peak of that war, we had a US administration that dealt in illegal drugs in order to buy weapons illegally from declared terrorists, and then illegally provided said weapons to counterinsurgency forces, explicitly violating the express will of Congress. And then the Vice President, a former CIA Director, who was nominally in charge of the operation, was subsequently elected President. And some years later, his youngest son, with no obvious qualifications for office, was elected President for two terms, and broght to his administration many of the advisers and operatives who had carried out the drugs-for-weapons program.
I mean, it's hard to make up stuff this this!
What do you point to, from the 70s through the present, that exemplifies the "rule of law" in actual practice?
I'm still struggling to figure out why a cohesive, widespread, community-driven solution hasn't emerged yet. Anybody have any ideas as to why?
- similar forces drive techies: would you rather make Facebook for free or for a billion dollars?
- tech culture doesn't understand community building
- some censorship / legal control is absolutely necessary lest you become the child porn network, or crown in spam
Arguably, "becom[ing] the child porn network" is the only proof that you can't be compromised. Because assholes will eventually migrate to the most secure options.
But in every other case that I'm aware of, OPSEC failure led to pwnage. Freedom Hosting. Silk Road 1. Sheep Marketplace.
So can you point to another case where defects in Tor design or practice got people pwned? I doubt it. But even so, I am concerned that the absence of such news just reflects parallel construction.
And finally, it's not enough to just rely on Tor. In my opinion, one should always use Tor through a nested VPN chain, comprising servers from at least three different VPN providers. That way, adversaries must compromise both Tor and the VPN services. Also, it's crucial to never run servers in places that can be associated with you. Because the more traffic there is, especially if an adversary can control traffic flow, the easier it is to do traffic correlation.
The problem is that actually implementing not-weak OPSEC is much harder than most people understand (even those with technical backgrounds). For example, is your "secret" activity on TOR easily tied to your non-secret activity from a search of network entry/exit times (i.e. "secret" activity is the complement "non-secret" activity)?
I recommend Zoz's DEFCON talk, "Don't Fuck It Up!"[1], for a very good overview of how hard OPSEC has become.

The easiest to use, most consistent and stable system is always going to be a centralised system and these cost money. Once money is involved it starts to become a company and be bound to the laws the countries want. Unless someone can solve the known problems with decentralised systems while simultaneously making the system as easy to onboard and use as the tech giants can we will never have a truly competitive open source equivalent the products of tech giants.
It doesn't need to be as easy to onboard and use. Freedom from censorship and surveillance is worth an awful lot of inconvenience in initial setup, and more people learn that every day.
The best I've come up with is a P2P mix network which used some covert channel. For plausible deniability, it would need to spread as malware, pretty much like WannaCry did (both virus-like and worm-like). But obviously, it wouldn't do anything horrible on inadvertently infected systems, except perhaps relay some traffic.
And yeah, it's a horrible idea. But what else is possible, if using unauthorized encryption itself becomes illegal?
Eventually, the elderly, uninformed US government is going to pass a law requiring a back door. And two things will happen:
- someone nefarious will get the private key, and do something nefarious with it. (Hopefully no one will die)
- offshore private messaging will become a thing.
There's a market for bith insecure-but-endorsed and secure-but-illegal, to be sure. And the 5 eyes will probably fight for decades to squash private messaging.
For a worst case scenario, see the war on drugs for an example of how this could go.
Eventually, the elederly, uninformed governments are going to die off, to be replaced with younger governments. Still uninformed, but hopefully less tyrannical.
> offshore private messaging will become a thing.
This won't have to happen. Just because the law says there has to be a backdoor doesn't mean open source software developers will comply. Develop your software anonymously, release it anonymously, and run it wherever you want. It doesn't need to be a service provided by a company in a foreign land, it can just be software you run on your own computer.
I don't think this is a reasonable thing to just hope for. Historically, governments have always had tyrannical streaks and I don't think it makes much sense to simply assert that "this time it'll be different". It probably won't.
It never used to be legal to be homosexual, for example, then it became socially acceptable, and then a generation of politicians had to die off, and then it became legal.
Problem is, in a worst case scenario ISPs could be compelled to proxy all traffic through government boxes for analysis. At that point any suspicious activity will probably be frowned upon.
So anyway, we went through this in the 90s (the Clipper Chip). That died down, in part because terrorists and criminals weren't really using much encryption. But now we have iPhones with strong encryption, and TLAs and LEOs are seriously freaked.
The fact they had the technological capability previously to act without Constitutional authority is irrelevant. Show up with a warrant or go pound sand.
In other words this notion of “get a warrant or pound sand” ignores that even with a robust legal warrant-requiring regime, they still would need to require back doors (key escrow, effectively the same thing) that would screw up security royally in order to get what they want.

Basically, crypto backdoors are a very bad idea.
Google's staggered updates to Chrome are updates sent to specific targeted users. The iOS App Store (and Google Play store, I believe) has an opt-in beta program that also sends betas to specific targeted users.
> If vendors are forced to abuse updates in this way then users are going to demand a certificate transparency-like system to stop the abuse.
But yes, leveraging users' trust in the update system is a risk that needs to be factored into the debate.
If trust is lost in the update mechanisms then something will be done to restore it. That would likely be large developers like Apple, Microsoft and Google deploying a technical solution to prevent themselves from sending different updates to different devices without loudly warning the user and automatically reporting the attack to the world. That would please users and reduce compliance costs. Really, the major operating systems should just do it now to prevent this from becoming a problem in the first place.
I always thought this would be a neat use of Ethereum: a smart contract publicly stores the hash+url of the latest version of $softwareProduct (and maybe also the hash+url for the latest beta release, etc). The software would only update to a version named by the smart contract. The smart contract would only allow the application developers' addresses to be able to update the published hash+urls. The smart contract could have arbitrary logic here, like to allow the developers to add new addresses that can publish new versions, or to implement voting logic so a majority of the developers have to agree on publishing a new version, etc. In this system, it's not possible to secretly push a malicious update to one user.
The EFF advises device makers to never enable automatic pull of updates. Because doing so would open the door for forced silent updates by court order.
Since you're already screwed if Microsoft is a bad actor, trusting their digitally signed updates doesn't increase your attack surface area. Well, it didn't. The Australian proposal adds Australia to the list of organizations you have to trust to accept updates signed by Microsoft.
Who is missing from that competition?
I'm purposely misconstruing the meaning, but it makes an ironic point. Remember that most of these tech companies make money by collecting and using the same data they claim to protect, and some provide it to the government.
If I write a chat app that uses strong encryption, with the keys stored on each user's device, there are no legal grounds for me to modify any part of my app if the government wants access.
Do you care to elaborate why this is Fascism? Why we should care? Or most importantly...
How do you respond to this instance of "Fascism"? Any ideas? Suggestions? Pointers? Calling it out is nice, but "calling Hitler a Nazi" is just an obvious Tautology. I expect better on HN.
