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T2,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 scheme of voting authentication for mobile sensor nodes using voting mechanism is proposed.Firstly, other nodes within the communication range of the node to be authenticated verify the identity information of the broadcast node, and then broadcast the voting information after passing the verification. When the number of approvals reaches the threshold T1 , And other nodes pass the authentication of the node and accept the request of network access.When the node moves, it makes full use of the verification results that have been carried out when the node enters the network and performs authentication and voting on the nodes to be verified, the number of approvals reaches the threshold T2, Verification.The simulation results show that under the premise of ensuring the security in node authentication process, the scheme needs less communication data volume than the other three contrast schemes, and can reduce the energy consumption of node broadcast authentication better, meanwhile, Has good low energy consumption.
