Ian Avrum Goldberg (born March 31, 1973) is a cryptographer and cypherpunk. He is best known for breaking Netscape's implementation of SSL (with David Wagner),[1] and for his role as chief scientist of Radialpoint (formerly Zero Knowledge Systems), a Canadian software company. Goldberg is currently a professor at the David R. Cheriton School of Computer Science, within the University of Waterloo. He was formerly Tor Project board of directors chairman,[2] and is one of the designers of off the record messaging.[3]

Education[edit]

He attended high school at the University of Toronto Schools, graduating in 1991. In 1995, he received a B.Math from the University of Waterloo in pure mathematics and computer science. He obtained a Ph.D. from the University of California, Berkeley in December 2000. His thesis was entitled A Pseudonymous Communications Infrastructure for the Internet.[4] His advisor was Eric Brewer.

Accomplishments[edit]

As a high school student, Goldberg was a member of Canada's team to the International Math Olympiad from 1989 to 1991, where he received a bronze, silver, and gold medal respectively.[5] He was also a member of University of Waterloo team that won the ACM International Collegiate Programming Contest in 1994.[6] In 1998, Wired Magazine chose him as a member of the "Wired 25".[7] In 2011 he won the EFF Pioneer Award.[8] In 2019, he won the USENIX Security Test of Time Award along with his colleagues David Wagner and Randi Thomas and former PhD supervisor Eric Brewer. [9]

Work in cryptography[edit]

In 1995, Goldberg with David Wagner discovered a flaw in the random number generator used for temporary key generation in the SSL implementation of Netscape Navigator.[1][10]

One of the first cryptanalyses on the WEP wireless encryption protocol was conducted by Goldberg with Nikita Borisov and David Wagner, revealing serious flaws in its design.[11][12]

Goldberg was a co-author of the Off-the-Record instant messaging encryption protocol. He is also the author of the Perl script included in the novel Cryptonomicon by Neal Stephenson.[13]

In 2009 Goldberg was co-author of the Sphinx Mix Format,[14] which is nowadays implemented with the extension of a per-hop payload to increase the privacy of both payer and payee while routing Bitcoin payments through the Lightning Network.[15]

Vitalik Buterin, co-founder of Ethereum, was a research assistant of Goldberg while a student at the University of Waterloo.[16]
