Abstract
Wireless Sensor Networks (WSN) is vulnerable to node capture attacks in which an attacker can capture one or more sensor nodes and reveal all stored security information which enables him to compromise a part of the WSN communications. Due to large number of sensor nodes and lack of information about deployment and hardware capabilities of sensor node, key management in wireless sensor networks has become a complex task. Limited memory resources and energy constraints are the other issues of key management in WSN. Hence an efficient key management scheme is necessary which reduces the impact of node capture attacks and consume less energy. In this study, we develop a cluster based technique for key management in wireless sensor network.

We have developed an efficient technique for key management in the wireless sensor network
Summary
A network comprising of several minute wireless sensor nodes which are organized in a dense manner is called as a Wireless Sensor Network (WSN). Every node estimates the state of its surroundings in this network. Monitoring and tracking are the fields where the sensor networks are utilized. Several low power sensors are distributed across the location that is to be monitored in the sensor network (Saravanan et al, 2011)
