Node capture attack in Wireless Sensor Network: A survey

Wireless Sensor Networks (WSNs) is an emerging and powerful technique for today's real world applications with interactive environments. The application of wireless sensor network starts from environment, household monitoring and ranging up to critical military applications. As their application involving in transmitting critical information, which require challenging methods to provide security for WSNs. Among various attacks in wireless sensor network, node capture attack is a serious attack through which an intruder can performs various operations on the network and can easily compromise the entire network. Node captures attack s one of the hazardous attack in WSNs. The wireless sensor network requires robust mechanism to improve the detection of node capture attack. Our survey analyzes various protocols and detection schemes to propose a new technique to achieve network resilience against node capture attacks.
