Amit Sahai, a professor of Computer Science and Mathematics and the holder of UCLA’s Symantec Endowed Chair in Computer Science, has been selected as the 2023 Test of Time Award recipient for his paper titled “Efficient Non-interactive Proof Systems for Bilinear Groups.” This award is given to one research paper from the CRYPTO and Eurocrypt conferences 15 years after publication. He proposed a new type of non-interactive proof system that is more efficient than previous methods. The paper focused on bilinear groups, which are mathematical structures used in cryptography. Sahai has also won the International Association for Cryptologic Research (IACR) Test of Time Award for his paper “Fuzzy Identity-Based Encryption” in 2020. Professor Sahai will receive the award next week at the Eurocrypt conference in Lyon, France.

Professor Sahai serves as an Advisor to the Prison Mathematics Project. His primary research interests are in cryptography, coding theory, complexity theory, and security. The co-inventor of attribute-based encryption, functional encryption, and indistinguishability obfuscation, he has received many other notable awards in the past including the 2016 Lockheed Martin Excellence in Teaching Award from the Samueli School of Engineering at UCLA. He is also a Simons Investigator (2021), Fellow of the Association for Computer Machinery (ACM) (2018) and a Fellow of the IACR (2019).
