Professional Activities

I am a member of the editorial board of the USENIX Journal of Election Technology and Systems (JETS).

In January, 2014, I signed an open letter from US researchers in cryptography and information security: masssurveillance.info.

Brief Biography

Hovav Shacham joined UC San Diego’s Department of Computer Science and Engineering in Fall 2007.

Shacham received his Ph.D. in computer science in 2005 from Stanford University, where he had also earned, in 2000, an A.B. in English. His Ph.D. advisor was Dan Boneh. In 2006 and 2007, he was a Koshland Scholars Program postdoctoral fellow at the Weizmann Institute of Science, hosted by Moni Naor.

Shacham’s research interests are in applied cryptography, systems security, privacy-enhancing technologies, and tech policy.

In 2007, Shacham participated in California Secretary of State Debra Bowen’s “Top-to-Bottom” review of the voting machines certified for use in California. He was a member of the team reviewing Hart InterCivic source code; the report he co-authored was cited by the Secretary in her decision to withdraw approval from Hart voting machines.
