【摘要】 广播是无线传感器网络的重要通信手段,广播消息的安全性应得到保障。在分簇传感器网络结构基础上提出了一种无线传感器网络广播认证方案,簇头节点对广播进行签名认证,簇内使用消息认证码进行消息认证,网关节点负责广播消息在簇间的传递。分析表明,与部分现有的传感器网络广播认证方案相比,该方案以较低的能耗提供了较高的安全性。更多还原

【Abstract】 Broadcasting is an important method of communication in wireless sensor network and the security of broadcast message should be satisfied.This paper proposed a broadcast authentication scheme for wireless sensor networks using clustering structure,only cluster heads performed the expensive signature verification and broadcasted the message in cluster with MAC,normal nodes in the cluster checked the MAC using hash function and the gateway nodes in the cluster broadcasted the message to neighbor cluster heads located in their communication range.Compared with existing broadcast authentication schemes,the proposed scheme achieves high performance of security with lower energy cost.更多还原
