Unscientific dogma: Mother nature is telling us through Taiwan's drought to slow down and redesign chips to be secure.

My late model American vehicle is my home. Earlier this week, the locks kept popping open when I was trying to go to sleep. Nobody else besides me has a remote entry key.

I hopped into a Jeep Cherokee that I thought was mine and drove it down the road for a minute before realizing I was not in my vehicle. Keys are funny like that.

You'd think keyfob security would be worked out by now (just look at the prevalence of skeleton key software defined radios amongst the grayhat crowd). There's probably a limitation in security complexity due to limited power availability in the keyfob.

How can that be an argument, when we can sign secure transactions using RFID?

Ah, cool. Sounds like there's no excuse. My mistake.

I mistakenly assumed you'd need some kind of cryptographic key signing handshake via active electronics from within the keyfob to achieve secure comms with the host vehicle, and that such a requirement may have been some kind of implementation limiting factor, security-wise.
