The sensitivity of the potential WSN applications and because of resource limitations, key management emerges as a challenging issue for WSNs. One of the main concerns when designing a key management scheme is the network scalability. Indeed, the protocol should support a large number of nodes to enable a large scale deployment of the network. The proposed system is a new scalable key management scheme for WSNs which provides good secure connectivity coverage. For this purpose, make use of the unital design theory.
