The Mersenne Low Hamming Combination Search Problem can be reduced to an ILP Problem

Abstract

In 2017, Aggarwal, Joux, Prakash, and Santha proposed an innovative NTRU-like public-key cryptosystem that was believed to be quantum resistant, based on Mersenne prime numbers q = 2^N-1. After a successful attack designed by Beunardeau, Connolly, Geraud, and Naccache, the authors revised the protocol which was accepted for Round 1 of the Post-Quantum Cryptography Standardization Process organized by NIST. The security of this protocol is based on the assumption that a so-called Mersenne Low Hamming Combination Search Problem (MLHCombSP) is hard to solve. In this work, we present a reduction of MLHCombSP to Integer Linear Programming (ILP). This opens new research directions for assessing the concrete robustness of such cryptosystem. In particular, we uncover a new family of weak keys, for whose our attack runs in polynomial time.
