基于配对的无线网快速密钥协商协议

Fast key agreement protocols for wireless networks based on bilinear pairings

针对低频无线网通信速率低、时延长等特点,提出了一套用于移动终端与中心节点动态数据传输的密钥管理协议,单轮消息交换即可完成密钥协商,并提出了降低终端运算量的改型方案。协议满足前向安全性、会话密钥泄露的安全性、个人密钥泄露的安全性,无不明密钥共享,单方不能控制密钥生成。

A kind of key agreement protocols is proposed for low frequency wireless networks with low band width and long latency,in which a common session key is obtained after one round exchange.An improvement is presented to decrease the computation cost for the mobile terminals.The protocols provide known session key security,part forward secrecy,and there is no keycompromise impersonation,no unknown key-share and no key control.
