Undeniable signatures based on isogenies of supersingular hyperelliptic curves

This work addresses cryptographic security for applications requiring non-repudiation, but it appears incremental as it builds on existing isogeny-based methods.

The authors tackled the problem of designing an undeniable signature scheme by proposing a new scheme based on supersingular hyperelliptic curves of genus 2, but no concrete results or numbers are provided in the abstract.
