基于双线性对的域间认证与密钥协商协议

Transdomain authentication and key agreement protocol based on bilinear pairings

结合代理签名和签密方案的特点,以双线性对为工具,设计了一个域间电子商务的认证与密钥协商协议。该协议能够实现移动用户与服务提供商之间的双向认证和移动用户的匿名性,并且会话密钥保持了新鲜性,做到一次一密钥,保证了协议的公平性和实用性,能够克服重放攻击、拒绝服务攻击、中间人攻击和密钥泄漏假冒攻击。

A transdomain authentication and key agreement protocol based on bilinear pairings was proposed combining the merits of the proxy signature and signcryption. Mutual authentication between mobile user and service provider, anonymity of the mobile user and freshness of the session key was realized, which provided fairness and practicability, and avoided replay attack, denial of service attack, man-in-middle attack and key-compromise impersonation.
