摘要：We propose two public-key schemes to achieve deniable authentication for the Internet Key Exchange(IKE). Authentication in security had is the essential factor in the key establishment over Internet. The DeniableInternet key exchange protocol gives more value to the IKE standard. Our schemes can in some situations be moreefficient than existing IKE protocols as well as having stronger deniability properties. Key-exchange, in particularDiffie–Hellman key exchange (DHKE), is among the core cryptographic mechanisms for ensuring network security.For key-exchange over the Internet, both security and privacy are desired. In this paper, we develop a family ofprivacy-preserving authenticated DHKE protocols named deniable Internet key-exchange (DIKE), both in thetraditional PKI setting and in the identity-based setting. The newly developed DIKE protocols are of conceptual clarityand practical (online) efficiency. They provide useful privacy protection to both protocol participants, and add noveltyand new value to the IKE standard.
