摘要: 密钥协商协议是在公开的信道上,两个或多个参与方之间共享密钥的机制。设计了一个利用Weil配对的基于身份的三方密钥交换协议,协议能完全满足密钥交换协议要求的安全特性,且具有更高的效率。

Abstract: A key exchange protocol is designed to allow entities establishing a session key to encrypt data over an open network.This paper presents an identity-based tripartite key exchange protocol from Weil pairing.The protocol provides the desired security attributes of an authenticated key exchange protocol.Compared with the previously proposed protocols,it reduces the computational cost.
