Abstract

The ring signature scheme has an important usage area of public key crypto-system. It can be used for e-voting, as well as leaking information without revealing identity within a group. However, most of these systems relies on traditional crypto-systems which are not secure against quantum computing related attacks. Multivariate cryptography is one of the most popular research areas on quantum resilient crypto-systems. In this work, we propose an efficient ring signature scheme based on GeMSS, where we achieve smaller signature size and faster verification time with respect to other alternatives.
