Secure and efficient key management protocol (SEKMP) for wireless sensor networks

Wireless sensor networks (WSNs) are used in the many critical applications, such as, military, health, and civil applications. Sometimes such applications require that the WSNs to be randomly deployed in inaccessible terrains such as a remote territory. As a result, the sensors are left unattended and become a potential target for an adversary. Therefore, we propose a highly Secure and Efficient Key Management Protocol for WSN, called SEKMP. The proposed protocol (SEKMP) adapts a new key management approach by leveraging the advantages of asymmetric cryptography and employs them in a very efficient way for delivering the session key to sensor nodes.
