提出一种新的动态无线传感器网络安全时钟同步算法DSCS(Dynamic Secure Clock Synchronization).DSCS采用本地广播认证的方案阻止网络外部的恶意节点的攻击,同时采用接收冗余的同步报文的方案阻止网络内部妥协节点的攻击,解决了无线传感器网络时钟同步算法中的安全问题,并且适用于动态网络.仿真结果验证了DSCS算法的高效性.
A novel scheme called Dynamic Secure Clock-synchronization (DSCS) is proposed for wireless sensor networks (WSN). As a result, the attacks from the outside malicious nodes are blocked due to a local broadcast authentication scheme while the attacks from the inside compromised nodes are prevented by the redundant synchronization messages. The two solutions make DSCS secure and resilient. DSCS is fit for both dynamic and static networks. The simulation results present the great efficiency of DSCS.
