Allow me to introduce you to the M.A.D. Cats’ Official
Team Scientist, Whitfield Diffie.
Sometimes people are so brilliant that they break the system. His grades sucked. But his test scores were so high that he was admitted into MIT’s math program anyway as a non-legacy from Jamaica, Queens. During those undergrad years, he also worked for MITRE where he was one of the early pioneers behind MATHLAB. After graduation, Diffie went to work at the Stanford AI lab. That is where his lifelong interest in cryptography extended to computers. But 50+ years ago, almost all quality research was classified. So Diffie "went around doing one of the things I am good at, which is digging up rare manuscripts in libraries, driving around, visiting friends at universities."
While meeting with a friend at IBM Research Headquarters, it was suggested to Diffie that he meet with an electrical engineering prof from Stanford named Martin Hellmann. Long story short, Diffie-Hellmann key exchanges and the resulting 1976 paper are the backbone of public computer cryptography. You don’t have a functioning modern internet without him.
He’s got a laundry list of career accomplishments ranging from being the Chief Security Officer at the monolith that was peak Sun Microsystems for 3 decades to being an exec for ICANN (the non-profit that essentially regulates internet domains). So many of the most accomplished computer scientists of that era look worse as people as the years go by. But not this one. As a mutual friend once told me, “Whit is the exact same person he was in the 70s. He just has nicer suits now.” So every time you make a transaction or log into a website, think of how this is only an option for you because of a guy who was tossed out of grad school at Stanford because he didn’t feel like taking a physical.
