无线传感器网络复件攻击的移动检测方法

无线传感器网络无人值守的特性使得它易于遭受复件攻击从而造成严重的安全隐患。提出了一个移动检测复件攻击的方法，通过检测节点的移动使得网络内的每个节点都能直接与检测节点通信，从而使得检测节点与一跳范围内的传感器节点能够直接通信，从而全局地检测到网络中的复件攻击节点，并采用更新网络对称密钥的方法防御逃避检测的节点。实验表明该方法能够检测到网络内的所有复件攻击节点，和其他方法相比，本方法不需要检测消息的转发，检测开销小并且实现了开销在网络中的均衡。

Mobile detection of replication attacks in wireless sensor network

The detection schemes proposed so far are not satisfactory because they are energy and memory demanding,not suit for use in resource-constrained wireless sensor networks.the detection of replica attack was focused on in WSN.from the intuition that mobility,in conjunction with the one-hop sensor node’s communication,helps detect the replica attack globally.Then,propose a mobile detection method to detect the replica attack.Analysis and simulations result show that the our method helps to detect replica attacks effectively and efficiently,with a small and well-balanced overhead in the network.
