Detection of Node Replication Attack in MSN Based On PKI

In these days, randomly moving sensor networks are used for building up a application in all the areas like industrial, environmental, and medical and so on. There are some disadvantages of this network over the WSN, this network faces the problem regarding the security attack and they create clones of the nodes. They face this problem because of their dynamic nature. There are some solutions for noticing the attack of node replication. The sensor node generally does not assemble with tamper resistant hardware. This permits the circumstances where the competitor can easily compact the sensor node. There are number of approach are done for noticing node replication offense. The methods like localize algorithm, resisting node replication attack in mobile sensor networks. In this paper we introduced PKI based method for detecting node replication attack. This method improved the localized algorithm and settles the node attack. The proposed system consist of localize algorithm for detecting node replication attack and algorithm to protecting the node replication attack with less storage requirement, processing control and communication transparency.
