E.Verheul proved that existence of a pairing inversion and a distortion map implies that the computational Diffie-Hellman problem is feasible. Recently some other formulations of a pairing inversion are proposed. We study their relations.

    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[…]
