摘　　要：随着无线传感器网络在社会各个领域的渗透,其安全机制的研究一直是无线传感器网络的研究热点。在分析了无线传感器网络中认证及密钥协商方案设计时应满足条件的基础上,基于单向HASH函数和对称密码算法,设计了无线传感器网络中传感器节点间一种高效的认证及密钥协商方案。并从互认证、会话密钥、可抵御攻击等方面对该方案的安全性进行了分析,说明了该方案的安全性能较好,可有效抵御典型攻击行为;详细比较该方案和现有类似方案的运行性能,结果表明,该方案在存储容量需求、计算复杂性和通信带宽需求方面均优于现有方案。With the widely used of wireless sensor networks in all areas of society,the security mechanisms of wireless sensor networks has been the focus of research.An efficient wireless sensor networks authentication and key agreement scheme is designed based on the one-way hash function and symmetric cryptographic algorithm.After the analysis of the mutual authentication,session key and anti-aggressive of the scheme,the scheme has strong security feature and can resist the typical aggressive activity.Through the comparison between the scheme and the existing schema on the running efficiency,the results show the scheme is superior to existing scheme in the storage capacity requirements,computational complexity and communication bandwidth requirements, etc.
