In response to the need for secure one-round authenticated key exchange protocols providing both perfect forward secrecy and full deniability, we put forward a new paradigm for constructing protocols from a Diffie-Hellman type protocol plus a non-interactive designated verifier proof of knowledge (DV-PoK) scheme. We define the notion of DV-PoK which is a(More)
The most widely accepted models in the security proofs of Authenticated Key Exchange protocols are the Canetti-Krawczyk and extended Canetti-Krawczyk models that admit different adversarial queries with ambiguities and incomparable strength. It is desirable to incorporate specific and powerful adversarial queries into a single unified security model and(More)
