GROUP KEY MANAGEMENT FOR MULTICAST COMMUNICATION IN WSN

Abstract

Wireless Sensor Network contains nodes with limited storage, energy and Computation power. WSN applications are spread in several areas etc. military, Agriculture Science3 and the environment Science. In WSN network, motes communicate with each other in secure mode and to achieve this the usual messages send to the other node after encryption. A major challenge in WSN is securing communication. Various algorithms have already been proposed in this regard by many researchers. WSN uses a variety of applications of various sizes in a range of environments. Secure communication that uses WSN by many applications, key management is essential to meet the security objectives by joint and leaving operations of the node. Information is broadcasted from one node in a cluster to another via the cluster head in multicast WSN, where information security is an important concern and cryptographic algorithms play a critical role. RSA and CRT are combined in a Dynamic Cluster-Based Group Key Management Scheme (DCGKMS) to provide hybrid security. Based on the evaluation parameters such as computing, communicating, and rekeying cost, the recommended DCGKMS is secure, effective, and cost-efficient. Simulated results are shown in comparison to LKH and OFT using NS2. There are several WSN applications used many areas like military applications, agriculture, and environmental monitoring. Sensors connected to wireless networks transmit sensitive data over insecure channels, exposing the data to several threats. In group communication, there are various challenges. Group key management has significant security requirements, as well as techniques for securing it. A comparison of the traditional systems that have been carried out and appraised is being done. The study finishes with open research talks on the best ways to reduce critical expenditures during leave and join operations.
