(PDF) Better Bootstrapping in Fully Homomorphic Encryption

WebGentry’s “bootstrapping” technique (STOC 2009) constructs a fully homomorphic encryption (FHE) scheme from a “somewhat homomorphic” one that is powerful enough to evaluate its own decryption function. To date, it remains the only known way of obtaining unbounded FHE. WebNov 9, 2016 · In a somewhat encryption scheme, the number of homomorphic operations is limited, but can be made asymptotically large using bootstrapping [ 15 ]. This technical trick introduced by Gentry allows to evaluate arbitrary circuits by essentially evaluating the decryption function on encrypted secret keys. toyota north east calgary

Webinto three steps: a general“bootstrapping”result, an“initial construction”using ideal lattices, and a technique to“squash the decryption circuit”to permit bootstrapping. Our research began with the second step: a PKE scheme E1 described in Section 3 that uses ideal lattices and is homo-morphic for shallow circuits. A ciphertext ...

The FHEW (11) scheme was the first to show that by refreshing the ciphertexts after every single operation, it is possible to reduce the bootstrapping time to a fraction of a second. toyota north edsa hotline

WebGentry’s FHE bootstrapping 4/29. The evolution of FHE Fully Homomorphic Encryption has seen drastic changes since Gentry’s rst proposal: I [Rivest,Adleman,Dertouzos’78]: Open problem I [Gentry’09]: ideal lattices, sparse subset-sum, squashing, etc. Webbootstrapping is to homomorphically evaluate the decryption circuit. The works that followed Gentry’s publication were aimed at proposing new schemes or at improving the bootstrapping in order to make FHE more efficient in practice. The most famous constructions are DGHV [11], BGV [5], GSW [16], and their variants. toyota north columbus ohio toyota north edsa

WebGentry then shows how to slightly modify this scheme to make it bootstrappable, i.e., capable of evaluating its own decryption circuit and then at least one more operation. Finally, he shows that any bootstrappable somewhat homomorphic encryption scheme can be converted into a fully homomorphic encryption through a recursive self-embedding.
