Detecting node replication attacks in wireless sensor networks: Survey

Abstract

Wireless Sensor Networks has collection of sensor nodes. The sensor nodes may be captured by the attacker because the nodes are spread out in unattended surroundings. The attacker collects all secret information such as key, secret credentials, etc. and replicates the node. This replicated node is also called as Clone node. In this paper, an attack called as node replication attack is discussed. The clone node or replicated node behaves as a legitimate node. The clone node can damage the network. In node replication attack, detecting the clone node is an important issue in Wireless Sensor Networks. In this survey, the existing detection schemes by researchers are discussed.
