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。
The key agreement protocol is a mechanism for sharing keys between two or more participants on a public channel. An identity-based three-party key exchange protocol using Weil pairing is designed. The protocol can fully satisfy the security features required by the key exchange protocol and has higher efficiency.
