A New Efficient and Strongly Secure Authenticated Key Ezchange Protocol

摘要：

In 2007, LaMacchia et al.proposed the extended Canetti-Krawczyk (eCK) model for authenticated key exchange (AKE) protocols. In this paper, we first modify the eCK model by adding a new query to make the adversary can reveal all ephemeral secret information. Then we propose a new efficient and strongly secure AKE protocol in the asymmetric setting, called E-NETS (enhanced NETS) protocol, and prove its security in the modified eCK (meCK) model under the random oracle assumption and the gap Diffie-Hellman assumption.
