]. Wireless Sensor Networks (WSNs) consist of numerous
such sensor nodes that set up a network among themselves in
an adhoc manner. Wireless sensor networks are generally
deployed in inhospitable terrain. Thus there are several
challenging issues that need to be dealt with. These include
unattended operation, untethered for energy and
communication, dynamic environment and adhoc deployment,
among many others [3, 4]. Among these issues, security and
energy reign at the top. This work deals with the issue of
security in WSNs.
