基于改进EDD算法的无线传感器网络克隆攻击检测方法

Detection Method for Clone Attack in Wireless Sensor Networks based on Improved EDD Algorithm

无线传感器网络中节点的安全性是一个富有挑战性的课题。节点复制攻击是众多攻击手段中的一种,攻击者从一个节点捕获安全证书,可以使用相同的ID来复制节点。当网络中出现很多复制节点时,就会影响系统的正常运行。为了克服这个问题,提出了改进的高效分布式检测算法IEDD(Improved Efficient Distributed Detection)。它将EDD算法和人工免疫系统危险理论相结合,以检测克隆攻击,从而防止在无线传感器网络中出现多个副本。仿真实验表明,这种方法提高了检出率,降低了管理费用,且具有更高的数据包投递率和更低的能耗。

The security of nodes in wireless sensor networks is a challenging task. Node replication attack is one of the many attacking methods, the attacker captures security certificate from a node and use the same ID to copy the node. Lots of replica nodes appearing in the network, would affect normal operation of the system. In order to overcome these problems, this paper proposes an efficient distributed detection algorithm IEDD （Improved Efficient Distributed Detection）. It combines the EDD algorithm with the artificial immune system to detect the clone attack, and thus to prevent multiple copies in wireless sensor networks. Simulation results show that this method can improve detection rate, reduce management costs, and has a fairly high packet delivery ratio and low energy consumption.
