We recall recent work on CM constructions using canonical lifts of the Frobenius isogeny: for p = 2 with Gaudry, Houtmann, Ritzenthaler, and Weng, and generalisation to p = 3 with Carls and Lubicz. I will explain how to extend this to (l,l)-isogenies for l = 2, 3 coprime to the characteristic.

    We provide a generic construction to turn any classical Zero-Knowledge (ZK) protocol into a composable oblivious transfer (OT) protocol (the protocol itself involving quantum interactions), mostly lifting the round-complexity properties and security guarantees (plain-model/statistical security/unstructured functions…) of the ZK protocol to the resulting OT protocol. Such a construction is unlikely[…]
