Cryptographic group actions and applications
WebAug 31, 2024 · Cryptographic group actions are a relaxation of standard cryptographic groups that have less structure. This lack of structure allows them to be plausibly quantum resistant despite Shor's algorithm, while still having a number of applications. The most famous example of group actions are built from isogenies on elliptic curves. Our main … WebCryptographic group actions have recently attracted much interest owing to their supposed quantum-resistance and to their versatility. Brassard and Yung [11] initiated the study of group actions in cryptography, but it was Cou- ... Among the many applications of CSIDH, we may cite the c IACR 2024.
