4 Brief of Homomorphic Polynomial Public Key Cryptography

In this section, we are going to briefly describe the motivation behind and development of the HPPK scheme: the path from the original deterministic polynomial public key or DPPK, proposed by Kuang in 2021[1], then multivariate polynomial public key or MPPK, proposed by Kuang, Perepechaenko, and Barbeau in 2022[5], to the homomorphic polynomial public key over a single hidden ring in 2023[6], and over a dual hidden ring scheme[7]. MPPK schemes for digital signature or MPPK/DS have been proposed by Kuang, Perepechaenko, and Barbeau in 2022[8], then an optimized version was proposed by Kuang and Perepechaenko in 2023[9]. A forged signature attack was reported by Guo in 2023[10].

4.4 MPPK DS

A digital signature scheme based on MPPK has been proposed by Kuang, Perepechaenko, and Barbeau in 2022[8] and later optimized variant was proposed by Kuang and Perepechaenko in 2023[9]. MPPK digital signature scheme originated from MPPK over a single prime field[3, 4]. The signature verification equation stems from the identity equation
