Fully Homomorphic Public-Key Encryption with Two Ciphertexts based on Discrete Logarithm Problem

Masahiro Yagisawa
Abstract

In previous paper I proposed the fully homomorphic public-key encryption based on discrete logarithm problem which may be vulnerable to “m and -m attack”. In this paper I propose improved fully homomorphic public-key encryption (FHPKE) with composite number modulus based on the discrete logarithm assumption (DLA) and computational Diffie–Hellman assumption (CDH) of multivariate polynomials on octonion ring which is immune from “m and -m attack”. The scheme has two ciphertexts corresponding to one plaintext.
