Post-Quantum Key Agreement Protocol based on Non-Square Integer Matrices. (arXiv:2301.01586v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
We present in this paper an algorithm for exchanging session keys, coupled
with an hashing encryption module. We show schemes designed for their potential
invulnerability to classical and quantum attacks. In turn, if the parameters
included were appropriate, brute-force attacks exceed the (five) security
levels used in the NIST competition of new post-quantum standards. The original
idea consists of products of rectangular matrices in Zp as public values and
whose factorization is provably an NP-complete problem. We present running
times …
