In this paper; we propose a security protocol for sensor networks that provides good protection while taking into account the limited resources of the sensors. The protocol is based on an effective key management method with a minimum storage of keys. Our approach is based on the combination and improvement of two methods already proposed by the research community: cryptography based on elliptic curves and key management based on an AVL tree. Compared with RECC "A Routing-Driven Elliptic Curve Cryptography Based Key Management Scheme for Heterogeneous Sensor Networks" and CECKM "High-Effect Key Management Associated With Secure Data Transmission Approaches in Sensor Networks Using a Hierarchical-based Cluster Elliptic Curve Key Agreement" two methods based on Diffie-Hellman elliptic curve cryptography method, our approach provides a positive impact on reducing energy consumption and memory storage. It saves significant time and memory and it reduces the exchanged packets during keys installation with fewer processing operations.
