Distributed and Fast Detection of Mobile Replica Node Capture Attacks Using Sequential Hypothesis Testing For WSN

Security is important for many sensor network applications. Wireless Sensor Networks (WSN) are often deployed in hostile environments as static or mobile, where an adversary collects all the credentials like keys and identity. The attacker can reprogram it and replicate the node in order to eavesdrop the transmitted messages or compromise the functionality of the network. A harmful attack against sensor networks where one or more nodes illegitimately claims an identity as replicas is known as the node replication attack. This paper detects the node replication attack using Efficient Distributed Detection, Scheme and Game theoretic approach to improve the performance
