ePrint Report: Non-Interactive Commitment from Non-Transitive Group Actions

Giuseppe D'Alconzo, Andrea Flamini, Andrea Gangemi

Group actions are becoming a viable option for post-quantum cryptography assumptions. Indeed, in recent years some works have shown how to construct primitives from assumptions based on isogenies of elliptic curves, such as CSIDH, on tensors or on code equivalence problems. This paper presents a bit commitment scheme, built on non-transitive group actions, which is shown to be secure in the standard model, under the decisional …
