摘要：Key management in wireless sensor network is a challenging task because public key cryptosystem are unsuitable for using in resource constrained sensor nodes, and the nodes could be physically compromised by a rival. Due to resource co nstraints, it is infeasible to apply traditional key management techniques in WSN. Numero us dynamic key management schemes have been proposed so far, for maintaining secure channels among communicating nodes but they all are not efficient in terms o f resource constraints parameters. This paper proposes a dynamic key management scheme by combining the advantages of simple cryptography and random key pre-distribution scheme. In this, when distance between two nodes increases the remaining energy of nodes are also increases. This scheme enables to establish a secure links between any two co mmunicated nodes. Beside this, it also removes node addition attack and increases the security strength within the cluster by introducing the cluster key. Finally, the security analysis show that proposed scheme is more efficient and meets the security needs of sensor network
