摘　　要：两方跨域认证密钥协商协议是指来自不同私钥生成中心的两个参与方完成互相认证和协商出相同的会话密钥。基于身份的密码体制能避免公钥基础结构的公钥证书存储问题。双线性对运算复杂度较高,计算成本较大。我们提出了一个新的无双线性对基于身份的两方跨域认证密钥协商协议,并在随机预言模式下证明了协议的安全性。The two-party cross-domain authentication key agreement protocol that two parties belong to diffierent private key generators were able to complete the mutual authentication and produce same session key.The identity-based cryptosystem avoids the storage problem of public key certificate of public key infrastructure.Bilinear pairing have high computational cost.In this paper,a new identity-based two-party cross-domain authentication key agreement protocol without bilinear pairing was proposed.And the security of the new protocol was proved under the random oracle model.
