Gene Tsudik, Two Computer Science Ph.D. Students Develop Novel De-Authentication Prototype

Chancellor’s Professor of Computer Science Gene Tsudik and two of his Ph.D. students, Tyler Kaczmarek and Ercan Ozturk, have developed a novel technique aimed at mitigating “Lunchtime Attacks.” Such attacks occur when an insider adversary takes over an authenticated state of a careless user who has left his or her computer unattended. Tsudik, Kaczmarek and Ozturk have come up with an unobtrusive and continuous biometic-based “de-authentication,” i.e., a means of quickly terminating the secure session of a previously authenticated user after detecting that user’s absence. They introduce the new biometric, called Assentication, in a paper appearing at the 2018 International Conference on Applied Cryptography and Network Security (ACNS).

Gene Tsudik, ICS Exchange Students on International Team Studying Information Leakage

In a paper to appear at the 2018 European Symposium on Research in Computer Security (ESORICS), a team of researchers from UC Irvine, New York Institute of Technology and University of Padova (Italy) reveal a new attack: Secret Information Leakage from Keystroke Timing Videos (SILK-TV). The UCI researchers include Chancellor’s Professor of Computer Science Gene Tsudik and undergrad exchange students Martin Georgiev and Nikita Samarian.
