基于自验证公钥的安全高效WMNs密钥生成机制

Secure and efficient key generation scheme for WMNs using self-certified public key

针对无线mesh网络现有的密钥生成机制中,无法实现双向认证、会话密钥协商以及过度消耗节点资源的问题,结合基于椭圆曲线的密码体制和基于自验证公钥的密钥生成方法,提出一种可用于无线mesh网络的密钥生成机制。这种机制避免了密钥托管,可实现通信双方身份认证和会话密钥协商,具有抵抗常见攻击的安全属性。实验及分析表明,相比同类协议,具有更低的计算和通信代价。

In wireless mesh networks,the existing key generation schemes either failed to finish session key and authentication simultaneously or overspend nodes＇ resources. Based on elliptic curve cryptosystems and self-certified public keys,this paper proposed a new key generation scheme,which could be used in wireless mesh networks. In the scheme,there was no need for key escrow,participants could achieve mutual authentication and session key agreement simultaneously,it also could resist common attacks. The experiment and analysis results indicate that it needs lower communication and computation cost compared with similar protocols.
