基于簇的传感器网络节点复制攻击检测

当传感器节点布置在敌方区域并遭到敌人捕获时,敌方有能力破解传感器节点而得到其中所存储的重要信息.敌人一旦掌握这些信息,便可以复制一系列这样的节点且将其布置到网络中为进一步开展攻击作准备,这种入侵活动被称为传感器网络节点复制攻击.节点复制不同于诸如路由攻击一类的外部攻击,它直接危害传感器节点,破坏力强,给网络带来严重影响.在现有的分布式检测方法基础上提出一种基于簇结构的传感器网络节点复制攻击检测方案.仿真实验表明,改进的方案能对节点复制攻击做出有效判断,而且传输开销较现有检测方案要小.

Detection of Node Replication Attacks in Clustering-based Sensor Networks

Sensor nodes may be deployed in hostile environments. If an adversary captures a node, he may be able to access the private information within the node. The adversary then can replicate these sensors and deploy them in the network to launch a variety of attacks, these types of attacks are termed node replication attacks. Node replication attack differs from outsider attacks such as routing attacks, it directly attacks sensor node, spreading its influence throughout the network. Based on the existing distributed detection, a clustering-based scheme is proposed to detect node replication attack. Simulation results indicate that the proposed scheme can effectively detect node replication attack and it is more efficient than existing schemes as viewed from communication cost.
