无线传感器网络经常被部署在无人值守且严酷的环境中,攻击者能通过克隆节点来发起各种的内部攻击.本文提出一种新的分布式移动节点克隆攻击检测方法.仅当证人节点和被检测节点相遇或相关证人节点相遇时,检测信息被转发到证人节点进行检测.同时,利用序贯概率比检测技术,避免单一样本产生的高错误率.移动辅助的随机验证和序贯测试技术相结合,降低传统路由寻径开销和误警率/虚警率.仿真结果表明,协议具有较高检测效率和合理的开销.%Wireless sensor networks are often deployed in unattended and harsh environments to perform various mo-nitoring tasks. The adversary can launch node clone attacks to start a variety of insider attacks. This paper proposes a novel distributed protocol for detection of mobile replicas in wireless sensor networks. In our scheme, sensor's time-location claims are forwarded to obtain samples only when the corresponding witnesses meet. Meanwhile,se-quential tests of statistical hypotheses are applied to further detect the cloned node by witnesses. The combine of randomized verification based on encountering and sequential tests drastically reduces the routing overhead and false positive/negative rate for detection. Simulation results show the detection efficiency and reasonable overheads.
