| 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. |

| Abstract: |
| To achieve security in the networks, it is important to be able to encrypt and authenticate messages sent between the users. Keys for encryption and authentication purposes must be agreed upon by the users in the networks. Three new pairwise key agreement protocols based on Weil pairing are proposed in this paper. In those protocols, all the users share common secret information. They may arrange the pairwise key and authenticate each other by fewer messages. The proposed protocols have the security attributes such as known session key security, perfect forward secrecy, no key-compromise impersonation, no unknown key-share and no key control. |
