A new two-parties key agreement protocol based on identities in groups is proposed. For abelian groups this protocol is, in fact, the Diffie-Hellman one. We also discuss a general scheme producing matrix groups for which our protocol can have a secure realization.

    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[…]
