About me

Tancrède Lepoint is a cryptography engineer at Apple. He is also a director of the International Association for Cryptologic Research (2018-2023) and co-editor of the Cryptology ePrint Archive. Previously, he was a research scientist in the Private Computing team at Google, and a computer scientist at SRI International.

Tancrède drove the cryptographic deployment of the Exposure Notifications Privacy-preserving Analytics within Google, a multiparty computation system based on the private measurement system Prio. He also designed the verification flow for Exposure Notifications in the US. He worked on lightweigth anonymous credentials (trust tokens) and specializes in homomorphic encryption. Tancrède is also a coauthor of two post-quantum cryptographic primitives (CRYSTALS-Kyber and CRYSTALS-Dilithium), which are 2 of the 7 finalists considered for standardization by NIST.

His research interests include cryptography and security, privacy-enhancing technologies, homomorphic encryption, cryptographic protocols and implementation.

He holds a Ph.D. in Computer Science from École Normale Supérieure and University of Luxembourg.
