Sensor networks Localization; secure locations; secure key management


Wireless sensor networks have very promising future to many applications. Ensuring that sensor nodes locations are verified and are protected from malicious attacks will enable sensor networks deployment in mission critical applications. Due to the deployment nature, sensor nodes are highly vulnerable to localization attacks where an adversary can capture the nodes, changes its location or replaces it with a malicious node. In this paper we study this problem and present a secure localization scheme where nodes can securely locate themselves and send a message about their location to the neighboring nodes, eventually that message reaches the cluster leader and then to a secure base station. To find the location of nodes, we take advantage of triangulation method and protect the message transmission with a secure triple key management scheme.
