SPDH-Sign: towards Efficient, Post-quantum Group-based Signatures
Christopher Battarbee, Delaram Kahrobaei, Ludovic Perret +1
In this paper, we present a new diverse class of post-quantum group-based Digital Signature Schemes (DSS). The approach is significantly different from previous examples of group-b…
