Efficient Broadcast Authentication Using TSG Algorithm for WSN

Wireless Sensor Networks (WSN) is an emerging technology that has a wide range of applications including environment monitoring, medical systems, robotic exploration and smart places. In most of the sensor network sink node send broadcast information to all other sensor nodes. Broadcast authentication is an important security mechanism in a Wireless Sensor Network. Base station broadcast the public key to all the sensor nodes. Broadcast message authenticated by using public key. If single key is used throughout the life time, adversaries can easily listen to the communication between the sensor nodes and the base station. To overcome this short term keys are introduced.
