Faster Homomorphic Function Evaluation Using Non-integral Base Encoding

Abstract

In this paper we present an encoding method for xed-point numbers tailored for homomorphic function evaluation. The choice of the degree of the polynomial modulus used in all popular somewhat homomorphic encryption schemes is dominated by security considerations, while with the current encoding techniques the correctness requirement allows for much smaller… (More)
