This paper presents the design of a power- and area-efficient high-speed 768000-bit multiplier, based on fast Fourier transform multiplication for fully homomorphic encryption operations. A memory-based in-place architecture is presented for the FFT processor that performs 64000-point finite-field FFT operations using a radix-16 computing unit and 16 dual-port SRAMs. By adopting a special prime as...
The first plausible scheme of fully homomorphic encryption (FHE), introduced by Gentry in 2009, was considered a major breakthrough in the field of information security. FHE allows the evaluation of arbitrary functions directly on encrypted data on untrusted servers. However, previous implementations of FHE on general-purpose processors had very long latency, which makes it impractical for cloud computing...
