Craig Gentry (born 1973) [2] is an American computer scientist working as CTO of TripleBlind. He is best known for his work in cryptography, specifically fully homomorphic encryption . [ 3 ] [ 2 ] [ 4 ] [ 5 ]
Craig Gentry, using lattice-based cryptography, described the first plausible construction for a fully homomorphic encryption scheme in 2009. [9] Gentry's scheme supports both addition and multiplication operations on ciphertexts, from which it is possible to construct circuits for performing arbitrary computation.
For example, in 2009, Craig Gentry introduced the first fully homomorphic encryption scheme, which was based on a lattice problem. [ 13 ] Mathematical background
Craig Gentry: 2021 "For breakthrough research on fully homomorphic encryption and other fundamental contributions to cryptography." Yehuda Lindell: 2021 "For fundamental contributions to theory and practice of secure multiparty computation, for sustained educational leadership, and for service to the IACR." Josef Pieprzyk: 2021
The library implements the Brakerski-Gentry-Vaikuntanathan (BGV) fully homomorphic encryption scheme, as well as optimizations such as Smart-Vercauteren ciphertext packing techniques. [ 4 ] HElib is written in C++ and uses the NTL mathematical library .
is fully homomorphic if it is homomorphic for all circuits of size where is the scheme's security parameter. In 2009, Gentry [19] proposed the first solution to the problem of constructing a fully homomorphic encryption scheme. His scheme was based on ideal lattices.
In 2011 Brakerski and Vaikuntanathan based Fully Homomorphic Encryption (FHE) on LWE. [3] Together with Gentry, they constructed the Brakerski-Gentry-Vaikuntanathan (BGV) scheme, which can be instantiated in leveled mode without bootstrapping. [4] For these works, they were jointly awarded the Gödel Prize in 2022.
His work is focused on cryptography, including homomorphic encryption. He is the co-recipient of the 2022 Gödel Prize, together with Zvika Brakerski and Craig Gentry. [2] [3] He also co-founded the data start-up Duality, which utilizes technologies he developed revolving around homomorphic encryption. [4]
