An efficient authentication protocol and key establishment in dynamic WSN

A wireless sensor network (WSN) consists of thousands of sensors and one base station. Sensors are deployed in the network to monitor target area and sense information according to the applied application then send this information to the base station. Adversary can inject false information in the network or compromise the routing information between nodes or between nodes and base station. Thus make the wireless sensor network secure is considered a very important issue. This paper introduces an authentication protocol and simple key distributed scheme between sensor nodes. Node mobility has been taken into consideration and the work proposes a re-authentication protocol that is very efficient than the initial protocol.
