ajassp.2014.969.977.rar - 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.
