提出了一种采用投票机制的移动传感器节点的广播认证方案.首先待认证节点通信范围内的其他节点对其广播的身份信息进行验证,验证通过后再广播投票信息,当赞成票数达到阈值T1后,其他节点通过对该节点的认证,并接受其入网请求.当节点移动时,充分利用节点入网时已经进行过的验证结果,对待验证节点进行认证投票,赞成票数达到阈值咒,待验证节点通过验证.仿真结果显示,在保证节点认证过程中安全性的前提下,本方案较其他3个对比方案需要更少的通信数据量,可更好地减少节点广播认证消耗的能量,同时在存储消耗方面具有良好的低能耗性.
A voting mechanism based broadcast authentication scheme for the mobile sensor networks is presented. The identity of the broadcast is verified and voted by nodes within the communication range to be authenticated. If the number of pros surpasses threshold T1 , the node passes the authentication and joins the network. When the node moves, the mentioned above is used to assist authenticating. If the number of pros surpasses threshold T2 , the node passes the authentication. Simulation shows that as long as security is assured during the authentication process, the proposed program requires less communica- tion traffic thus consumes less energy than the three compared methods, the proposed method performs well on storage consumption with low-consumption.
