【摘要】 从增强网络安全性和降低节点能耗出发,论述无线传感器网络采用椭圆曲线密码体制进行密钥管理的必要性和可行性.基于椭圆曲线密码理论研究设计了一种适用于无线电传感器网络的可认证的新密钥协商协议,并对该协议进行验证分析,证明该协议能有效抵制节点被俘、消息重放和身份假冒等攻击,安全性高,消耗资源小,可扩展性强.更多还原

【Abstract】 This article argues that it is feasible to adopt elliptic curve cryptography in the process of key management of wireless sensor networks to guarantee their high network security and low energy consumption.A key negotiation protocol is proposed and its identity authentication is tested on the basis of ECC and Diffie-Hellman.The new protocol,with little resource consumption and great expansibility,can resist effectively attacks from node capture,message replay and impersonation.更多还原
