一类新的分布式随机验证无线传感网络节点克隆攻击检测

由于无线传感器网络节点的无人值守性,攻击者很容易捕获并复制节点,利用节点的安全证书把复制节点发布到无线传感器网络的各个角落,进而秘密发动各种攻击。提出一类新的分布式节点复制攻击检测协议,协议采用随机区域单元映射和域内随机线选验证相结合的方法进行攻击检测。仿真结果显示,协议的随机验证特性使网络能量消耗均匀,延长网络的生存周期。域内线选验证使协议的通信开销和储存开销较低并具有较高的检测率。

Node Clone Attacks Detection Based on Distributed Random Verification in Wireless Sensor Networks

It is easy for adversary to capture and compromise sensor nodes unattended nature in wireless sensor networks. In node replication attack, an adversary can take advantage of the credentials of the compromised node to surreptitious introduce replicas of the node into the network and launch many attacks. A novel distributed detection protocol of node replication attacks is presented. Randomly selected cells to which location claims are mapped and randomly linear-selected node verification in cell are combined in our method. Simulation results show that random verification is designed to balance the energy consumption and the lifespan of the networks is prolonged. High detection rate of node replication attacks and lower communication overhead are achieved.
