为了实现网络安全,一个重要的方法是网络用户传送加密和可鉴定的消息.此时,用来加密和鉴定的密钥应该由网络中的用户协商得到.提出了3个基于Weil对的成对密钥协商协议.在协议中,所有用户共享一个秘密信息,通过较少的步骤,同时实现密钥协商和用户认证.提出的协议满足如下的安全特性:部分密钥泄漏的安全性、完备的前向安全性、个人密钥泄漏的安全性、无不明的密钥共享和无法控制密钥等. In order to achieve network security, an important method is that network users send encrypted and authenticated messages, in which case the keys used for encryption and authentication should be negotiated by users in the network.Three pairs of Weil-based pairs Key Agreement Protocol In the protocol, all users share a secret information, through fewer steps, to achieve the key agreement and user authentication at the same time.The proposed protocol satisfies the following security features: partial key leakage security, complete Forward Security, Personal Key Leakage Security, Unidentified Key Sharing, and Uncontrollable Keys.
