Security & Privacy

09/12/2024 - UT professor Shravan Narayan, in collaboration with researchers from UC San Diego, Purdue, Google, Intel, Fastly, and Rivos, were finalists for the Intel Hardware Security Academic Award.Their publication, titled Going Beyond the Limits of SFI: Flexible and Secure Hardware-Assisted In-Process Isolation with HFI, presents HFI, a new extension for in-process isolation to current processors.

03/03/2023 - A methodology developed by UT professors will allow the cost of verifying computations to be reduced by batching many separate arguments together. Brent Waters, a computer science professor and a co-author of the paper, was inspired to find a more efficient way to verify computations by refining techniques that had already come out over a decade ago.

08/04/2022 - Privacy has become increasingly valuable and rare as technology has become more closely integrated with our lives. Private information retrieval (PIR) protocols allow you to retrieve information through an encoded query while also protecting your personal information. Our current security standard online can be viewed as a “no-privacy baseline,” which means the vast majority of our online information retrieval isn’t protected by any of these protocols. Cryptographers like UT Computer Science professor David Wu are building innovative solutions that support this growing preference for online privacy.
