The Cluster Replication Attack Detect Protocol Based On Bloom Filter

As the openness of the deployment area and the limited of the resource, wireless sensor networks are often faced with huge security hidden trouble.In the net,attacker can easily capture a sensor node, by analysising it, attacker can crack confidential information and generate a large number of replicas nodes that share the compromised node's ID.Then,attacker embed the replicas nodes in the network and make use of them to launch many attacks,which will lead to the paralysis of part or all of the network.Thus,it is very important to detect node replication and isolate them effectively.In this paper, aiming at the insufficiency of the traditional replica node attacks detect protocols,two replica node detect protocols are proposed.A Bloom-Filter-Based Clustering Protocol,namely the BFCP.The prtocol is divided into three phases:the cluster establishment phase,the local detection phase, the overall detection phase.In the local detection phase,the cluster heads use the Bloom Filter to collect the information in the cluster,alleviateing the storage overhead of cluster head node.In the overall detection phase,by using of cluster head to collect the inform ation and to isolate the replicas node,discarding the use of the traditional base station,balancing the network energy consumption,overcoming the problem of the single poi nt failure of base station.A Key Agreement of Bloom-Filter-Based Clustering Protocol,namely the KA-BF CP.Although the BFCP protocol saves the storage overhead of cluster head nodes and balances the network energy consumption,but as long as the replica node is not detected,the cluster head will unceasingly collect the information by communicating with the neighbor clusters,so that it is bound to bring a lot of storage overhead and communication overhead to cluster head nodes. As to relieve this problem,the KA-BFCP protocol is put forward.By banning the information fusion of adjacent cluster heads, the storage overhead of cluster head node is saved and the network lifetime is prolonged.By using some of the introduction mobile nodes to collect the information of cluster head node in the whole network,the detection probability of the replication node is improved.The simulation experiments show that, comparing to the traditional replication node detection protocol,the BFCP protocol and the KA-BFCP protocol in this paper i-mprove the detection rate and extend the life of the network.
