The Sunday morning 10am talk “The Mile High Club: Getting Root at 40,000 Feet” has been cancelled.  It is being replaced with:
Crypto Without Computers
Ben Agre
This is a study of the evolution of cryptography before computers, through what can be done today sans computer.  I will use this as a guiding principle through some of the earlier days of cryptography.  Beginning by looking at simpler attacks, moving on through the VIC cipher and the foundations of modern cryptography.
Secondly we will add and analyze twists to old classics making arguable to reason about the security of the modified constructions.
Finally we will take a moment and talk about what computers don’t do well, and propose some ideas on where you can play that computers can’t.
Ben Agre has dabbled in everything from VR, to OS development and a non trivial amount of crypto.  He tends to wander around and break things.
