基于椭圆曲线的多方密钥协商协议

摘要

密钥协商协议是在公开的信道上，2个或者多个参与方之间进行的共享密钥机制。利用安全单向函数，设计了一种基于椭圆曲线的多方密钥协商协议，协议能够满足密钥交换协议的安全特性，并且具有较高的计算效率。%The key agreement protocol is a shared key mechanism between two or more participants in a public channel. A multi key agreement protocol based on elliptic curve was designed by using the secure one-way function. The protocol was based on password authentication. The protocol designed can satisfy the security characteristics of the key exchange protocol, and has high computing efficiency.
