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
paper, we develop a cluster based technique for key management in wireless sensor
network.
