Security and Cryptography

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.
