David A. Wagner (1974) is an Assistant Professor of Computer Science at the University of California, Berkeley and a well-known researcher in Cryptography.
Wagner received an A.B. in Mathematics from Princeton University in 1995, an M.S. in Computer Science from Berkeley in 1999, and a Ph.D. in Computer Science from Berkeley in 2000.
Notable achievements include:
1995 Discovered a flaw in the implementation of Secure Sockets Layer in Netscape Navigator (with Ian Goldberg) [http://www.cs.berkeley.edu/~daw/my-posts/netscape-cracked-0].
1997 Cryptanalyzed the CMEA (cipher) algorithm used in many US cellphones (with Bruce Schneier).
1998 Development of Twofish encryption algorithm block cipher as a submission for NIST s Advanced Encryption Standard process (with Bruce Schneier, John Kelsey, Doug Whiting, Chris Hall, and Niels Ferguson).
1999 Invention of the slide attack, a new form of cryptanalysis (with Alex Biryukov); also the boomerang attack and mod n cryptanalysis (the latter with Bruce Schneier and John Kelsey).
1999 Cryptanalysis of Microsoft s PPTP tunnelling protocol (with Bruce Schneier and Mudge ).
2000 Cryptanalysis of the A5 (cryptography) stream cipher used in GSM cellphones (with Alex Biryukov and Adi Shamir).
2001 Cryptanalysis of WEP, the security protocol used in 802.11 WiFi networks (with Nikita Borisov and Ian Goldberg).
