In many critical applications of wireless sensor networks, the security of data exchanged between nodes is critical to ensure good functioning of networks and maintain their effectiveness. In this paper we propose a mobile algorithm to secure data transmitted by structured nodes in clusters. The idea is based on a mobile node with significant resources of calculations and energy, responsible for generation, management and periodic rekeying. The cryptography method used in this paper is based on elliptic curves and the key management is based on an AVL tree. However, the main challenges of this approach are to improve security and to increase network’s lifetime by minimizing the energy consumed by nodes belonging to a cluster while generating, storing keys and exchanging packets. To evaluate the performance of the proposed algorithm, we will compare the metrics simulation with two approaches based on elliptic curves: Driven Routing Key Management and Keys Management Method Based on an AVL tree.
