Appears in collection : 2024 - T3 - WS2 - Emerging topics in design and cryptanalysis of post-quantum schemes

Cryptography based on group actions has been studied for a long time. In recent years, however, the area has seen a revival, partially due to its role in post-quantum cryptography. In this talk, we present our work on a unified taxonomy of a variety of techniques used to design digital signature schemes. We describe all techniques in a single fashion, show how they impact the performance of the resulting protocols and analyse how different techniques can be combined for optimal performance. Everyone welcome!
