AUTHENTICATED CRYPTOGRAPHY PATENT NO.: 7,827,408
Message encryption and authentication are typically performed separately. In other words, a message is encrypted using one method and then a cryptographic hash of the message is generated using a second method. This invention is a device for and method of encrypting and authenticating a message and authenticating any additional information. The present invention provides a cryptographically stronger authentication method and is more efficient to implement, than the prior art.
VALUE: Provides combined authenticated encryption in efficient manner. Does not require random numbers, two encryption keys, or checksums.
A real good use case would be if you knew one of the two current processes was or was likely to become comprised.
Joe Witt is a smart guy who put a lot of work into making a robust workflow tool there.
As I was reading my thought was "Wow, NASA spends a lot of time making technology that would be really useful for spying on people."
What could possibly go wrong?! It's like a secret handshake.
