Scouting report
Wrote Applied Cryptography in 1994, the book that taught a generation of engineers how ciphers actually work, then designed Blowfish and co-designed Twofish. Spent the two decades after arguing the harder point: that security is a systems and incentives problem, not a maths problem. Coined “security theatre”, has written the Crypto-Gram newsletter since 1998, and helped report on the Snowden documents.
Curator’s note
More people entered this field because of one book than any other single cause.
