Cryptographic group actions and applications

WebIn this paper we propose efficient two-party protocols for obliviously applying a (possibly random) linear group action to a data set. Our protocols capture various applications such as oblivious shuffles, circular shifts, matrix multiplications, to name just a few. 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.
