Welcome to the web page for security
and cryptography research in
the Department of Computer Science and
Engineering at the University of
California at San Diego. Our group conducts research in areas
spanning from theory to practice: we work on the theoretical
foundations of cryptography; the development and analysis of
cryptographic protocols and algorithms; and on applied cryptography,
systems security, and network security. In line with our broad
security-related research interests, we are affiliated and actively
collaborate with both
the Theory
Group and the Systems
and Networking Group here at UCSD.

(8/10/09) Stephen Checkoway, in collaboration with Hovav
Shacham, Brian Kantor and their co-authors from Michigan and
Princeton, recently demonstrated a practical attack against the AVC
Advantage voting machine -- absent any access to source code and
overcoming a hardware architecture that prevents code execution from
DRAM. An introductory video can be found on the paper's page
here;
more info can be found in the Jacobs School press release here
or in their EVT'09 paper here.

(12/30/08) Lots of press for Tom Ristenpart's USENIX Security paper describing Adeona, a system that helps track stolen laptops in a privacy-preserving manner. A collaboration with University of Washington researchers including alumn Yoshi Kohno), Adeona has been downloaded by over 50,000 people and has been covered in reports ranging frm the San Francisco Chronicle to Slashdot. See Tom describe Adeona in this short video or read more in press releases from UCSD and UW.
