Security of wireless sensor networks plays an essential role in the application they used. Due to resource limitations of sensor node, such as energy supply and memory size, pairwise keys establishment between nodes are considered a difficult problem. This paper proposes a simple shared key discovery between sensor nodes in very clear steps. The authentication protocol provides both message and entity...
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...
