【摘要】 随着无线传感器网络研究的深入和不断走向实用,安全问题引起了人们的极大关注。无线传感器网络的诸多限制使得安全问题很难解决。给出了一种基于层次型拓扑结构的无线传感器网络的安全协议的设计方案。方案采用LEACH[1]算法的簇头选举方法,增加了对簇头身份的认证,采用动态变化的加密密钥及认证密钥,并讨论了实现过程中几个算法的选择。更多还原

【Abstract】 As the research on wireless sensor network is carried on and it is being brought into effect gradually,the security gains much attention.Because of the limits of wireless sensor network,the security is difficult to be solved.A design of security protocol for hier-archical wireless sensor network is proposed.The cluster-head elect method is adopted in LEACH [1] algorithm and identity authentication of the cluster-heads is added,and dynamic encryption and authentication keys are used to enhance the security.And then some algorithms of the implementation are discussed.更多还原
