In Wireless Sensor Networks (WSNs), because sensor nodes do not equip with tamper resistance hardwares, they are vulnerable to the capture and compromise performed by the adversary. By launching the node replication attack, the adversary can place the replicas of captured sensor nodes back into the sensor networks so as to eavesdrop the transmitted messages or compromise the functionality of the network. Although several protocols are proposed to defend against node replication attacks, all the proposed methods can only detect the node replication attacks probabilistically. In this paper, we propose Quorum-Based Multicast (QBM) and Star-shape Line-Selected Multicast (SLSM) to detect the node replication attacks, both of which can deterministically detect the replicas.
