| 摘 要： | 提出一种多PKG环境下无双线性对的基于身份AKA协议, 且在随机预言模型下, 将协议的安全性证明规约到标准的计算性CDH假设。提出了相应的基于身份XCR与DCR签名体制, 通过对两处体制进行安全性证明, 实现对新协议的安全性证明。通过与已有协议的相关性能比较体现了新协议的优点。

| Abstract: | The authors present an identity-based authenticated key agreement protocol without bilinear pairing in multiple PKG environments.Reduced to the standard computational Diffie-Hellman(CDH) assumption in the random oracle model,the protocol security is given a complete proof based on the security of proposed ID-based exponential challenge-response(XCR) signature scheme and dual challenge-response(DCR) signature scheme.Compared with previous identity-based authenticated key agreement protocols,the new protocol shows better performances. |
