For the sixth time in a row cryptovision employee Klaus Schmeh was a speaker at the renowned NSA Symposium on Cryptologic History in Washington, D.C. This event, organized by the NSA, brought together 350 experts from all over the world in mid-October, including numerous NSA employees. One of Klaus’ two lectures (on block ciphers) took place within a panel together with three well-known cryptology colleagues. One of them had contacted Schmeh a few weeks before the event and asked if he could participate in the panel: Whitfield Diffe, the co-inventor of the Diffie-Hellman key exchange and co-founder of asymmetric cryptography – and thus one of the most important computer scientists of our time. Klaus, of course, agreed, and the result was a prominent panel with exciting lectures and expert discussions, which was one of the highlights of the symposium.
