David A. Wagner (born 1974) is a Professor of Computer Science at the University of California, Berkeley and a well-known researcher in cryptography and computer security. He is a member of the Election Assistance Commission's Technical Guidelines Development Committee, tasked with assisting the EAC in drafting the Voluntary Voting System Guidelines. He is also a member of the ACCURATE project.

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.

He has published two books and over 90 peer-reviewed scientific papers. His notable achievements include:

  • 2007 Served as Principal Investigator for the source code review and also the documentation review of the historic California state Top-to-Bottom review of electronic voting systems certified for use. Flaws found with vendor-supplied voting machines resulted in decertification and provisional recertification by the Secretary of State.
  • 2001 Cryptanalysis of WEP, the security protocol used in 802.11 "WiFi" networks (with Nikita Borisov and Ian Goldberg).
  • 2000 Cryptanalysis of the A5/1 stream cipher used in GSM cellphones (with Alex Biryukov and Adi Shamir).
  • 1999 Cryptanalysis of Microsoft's PPTP tunnelling protocol (with Bruce Schneier and "Mudge").
  • 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).
  • 1998 Development of Twofish block cipher, which was a finalist for NIST's Advanced Encryption Standard competition (with Bruce Schneier, John Kelsey, Doug Whiting, Chris Hall, and Niels Ferguson).
  • 1997 Cryptanalyzed the CMEA algorithm used in many U.S. cellphones (with Bruce Schneier).
  • 1995 Discovered a flaw in the implementation of SSL in Netscape Navigator (with Ian Goldberg).
