摘要：A crucial problem in the security of wireless sensor network is that the nodes are subject to several kinds of attacks and threat like node replication attack, and it may bring serious consequence. To mitigate the damage brought by the node replication attack, in this paper, we propose a replication detection protocol that can discriminate the replicated nodes through detecting geographic fingerprints collision output from the bloom filter. If the receiver node found a conflicting location claim, that indicated there was an aggressor, then the node replication attack was detected. Moreover the usage of matrix decomposition ensured the security of the network, and also it provided the communication link verification.
