Wireless Sensor Network (WSN) is an emerging technology consisting of spatially distributed sensor nodes, which can cooperatively monitor physical or environmental conditions. The major resource constrain of WSN are, low processing, energy and storage capabilities. Broadcast is widely used communication method in WSN environment. In most of the sensor networks, the sink node sends broadcast information to all other sensor nodes. Broadcast authentication is an important security mechanism in WSN, as it allows mobile users to broadcast messages to multiple sensor nodes in a secured way.
