ePrint Report: New proof systems and an OPRF from CSIDH
Cyprien Delpech de Saint Guilhem, Robi Pedersen
Isogeny computations in CSIDH (Asiacrypt 2018) are described using a commutative group G acting on the set of supersingular elliptic curves. The commutativity property gives CSIDH enough flexibility to allow the creation of many cryptographic primitives and protocols. Nevertheless, these operations are limited and more complex applications have not yet been proposed.
When calling the composition of two group elements of G addition, …
