In this paper, the authors introduce a new paradigm to realize various types of cryptographic primitives such as authenticated key exchange and key encapsulation in the standard model under three standard assumptions: the Decisional Diffie-Hellman (DDH) assumption, Target Collision Resistant (TCR) hash functions and Pseudo-Random Functions (PRFs). They propose the first (PKI-based) two-pass Authenticated Key Exchange (AKE) protocol that is comparably as efficient as the existing most efficient protocols like MQV and that is secure in the standard model (under these standard assumptions), while the existing efficient two-pass AKE protocols such as HMQV, NAXOS and CMQV are secure in the random oracle model.
