PROVABLY SECURE IDENTITY-BASED AUTHENTICATED KEY AGREEMENT PROTOCOL AND ITS APPLICATION

摘要：

　　We point out the RYY+ identity-based (ID-based) key agreement protocol is vulnerable to Key-compromise impersonation (KCI) attack and Intermediate results leakage (IRL)attack.Then we give the improved protocol which provides KCI and IRL resistance.The novel protocol is provably secure under the gap Bilinear Diffie-Hellman assumption in the seCK model,which enhances the adversarys queries comparing with previous ID based AKE models.The proposed scheme also has an advantage over most previous schemes on security and efficiency.
