Dual Multivariate Polynomial Public Key Digital Signature

Dual prime with twin prime key modulo for multivariate polynomial public key digital signature algorithm is generated here.

Quantum computers are coming; NIST is leading the world to devise and standardize Post Quantum Cryptography (PQC) algorithms. In this study, we considered the Multivariate Polynomial Public Key (MPPK) Digital Signature (DS) algorithm as one of recent PQC algorithms and generated a subset or supset of the original prime numbers for MPPK/DS key pairs. The purpose is to reduce the semi-covariance correlation to increase its robustness against brute force attacks, MPPK may have lower semicovariance and thereby stronger robustness over traditional RSA and other PQCs like SPHINCS algorithms.
