| 摘 要： | 为解决跨域认证与密钥协商中存在的重复计算问题，提出一种基于跨域认证与密钥协商的协议模型。利用公钥加密算法，将跨域认证与密钥协商2种常用协议有机结合，以较少的计算资源、存储资源和网络带宽，在单一的协议内同时实现跨域认证和密钥协商的过程。理论分析和性能比较结果表明，该协议能够提供保密性、鉴别机制、完整性和不可抵赖性等安全保证，且具有较高的处理效率。

| Abstract: | In this paper,a new protocol which combines cross-domain authentication and key agreement together is proposed to solve the repeat computing problem in both procedures.Utilizing public key cryptography,the proposed protocol combines both cross-domain authentication protocol and key agreement protocol,and implements both functions in a single protocol with less computational resources,storage resources and network bandwidth.Theoretical analysis and performance comparison results show that the proposed protocol can provide confidentiality,authentication,integrity,nonrepudiation and other security guarantees.Besides,it has a high level of efficiency. |
