Recent hardware implementations of fully homomorphic encryption (FHE) exploit very high cardinality arbitrary moduli sets to parallelize large integer arithmetic. However, the benefit they gained are heavily offset by the slow residue-to-binary conversion due to the large modulo operations and limited number theoretic properties of arbitrary moduli. This paper presents a fast residue-to-binary (R2B)...
Large integer multiplication is a major performance bottleneck in fully homomorphic encryption (FHE) schemes over the integers. In this paper two optimised multiplier architectures for large integer multiplication are proposed. The first of these is a low-latency hardware architecture of an integer-FFT multiplier. Secondly, the use of low Hamming weight (LHW) parameters is applied to create a novel...
This paper presents an FPGA implementation of the Advanced Encryption Standard (AES), using a Minimal Instruction Set Computer (MISC) architecture. The MISC's architecture is simple and reconfigurable to execute fundamental instructions with just simple hardware logic components. Due to the MISC's simplicity, it can be further extended to data encryption systems for certain applications like wireless...
