【摘要】：针对混合云中用户群不同,认证机制不一致的特点,基于双线性对和密钥协商机制,提出了一种混合云联合身份认证和密钥协商协议,实现了混合云用户身份认证和授权策略等安全信息的分布式管理与动态获取。通过理论分析和实验证明,该协议具有安全高效的特点,可以有效预防篡改数据、伪造用户身份、重放和中间人攻击等,且以较小的计算量和通信开销,为混合云联合身份认证和密钥协商提供了一种较实用的解决方案。
[Abstract]:Based on bilinear pairings and key agreement mechanism, a hybrid cloud joint identity authentication and key agreement protocol is proposed for the different user groups and inconsistent authentication mechanisms in the hybrid cloud. Distributed management and dynamic acquisition of security information such as mixed cloud user identity authentication and authorization policy are implemented. Through theoretical analysis and experiments, it is proved that the protocol has the characteristics of security and efficiency, can effectively prevent tampering with data, forgery of user identity, replay and man-in-the-middle attack, etc. It provides a practical solution for hybrid cloud identity authentication and key agreement.
