Cluster-Based Trusted Secure Information Transmission in Wireless Sensor Networks

WSN is a heterogeneous system that gives Sensor Nodes access to the communications networks to record and analyze events at many locations. There are currently a number of key managing mechanisms in place to protect communication among Sensor Nodes. At the very least, the key management technique for any secured application needs to provide safety features like trustworthiness. Diffie-Hellman Key Exchange (DHKE) is vulnerable to Man-in-the-Middle (MITM) attacks due to lack of authentication. The Diffie-Hellman with Sybil Attack Prevention method is given as a solution to this issue. The goal of this technique is to identify and remove Sybil nodes from the network in order to address the previously stated problem. Several performance parameters, including packet delivery ratio, delay, throughput, and detection rate, are considered while evaluating the proposed work’s effectiveness. The results show that the proposed work is far better than the conventional techniques and has a better Sybil node detection rate.
