摘　　要：为确保信息在无线传感器网络安全传输,提出了一个新的基于群密钥的安全协议。通过离散对数和哈希链的使用,可确保信息不被攻击者伪造或窃取。同时,考虑到无线传感器网络是由大量能量有限的节点构成,其计算能力不高,生存周期较短的特性,为节省传感器电池能量,降低能源的消耗,在初始化阶段传感器节点发送数据前通过服务器来完成群密钥协商。经过实验和理论分析,所提出协议的安全和效率整体上优于其他协议。In order to guarantee the security of event update messages in transmission, a novel protocol is proposed based on the group key agreement. With the utilization of hash-chain keys and discrete logarithm, the attackers and malicious sensor nodes could not forge or modify the messages. Simultaneously, as the wireless sensor network is composed of massive low-energy sensor nodes with limited computing capacity and short life period, it is vital to save the battery energy and reduce the consumption. Therefore, in the initialization phase, namely before message transmission, the key agreement is completed with help of the server. Theoretical analysis and experiment verify that the proposed protocol is better than other protocols both in security and efficiency.
