Enhanced Secure Leach with Advanced Encryption Standard And Attack Detection Scheme

Wireless Sensor Networks (WSNs) have become widely used in a variety of applications, ranging from military surveillance to environmental monitoring, as a result of their quick development. However, WSNs are susceptible to security attacks due to their open communication channels and limited resources, which jeopardizes network dependability and data integrity. The network employs Abundant Secure LEACH protocol to create an energy-efficient system that is vulnerable to a wide range of assaults, including the HELLO flood. The proposed scheme uses Enhanced Secure-LEACH with Advanced Encryption Standard and Attack Detection (SLEAD) mechanism to protect cluster heads from sinkhole, sybil and Hello flood attacks and provide data privacy. SLEAD makes use of a unique ID for each sensor node and Advanced Encryption Standard Mechanism for the purpose of authenticating a sensor node as CH and ensure the security of data. SLEAD algorithm was implemented using Python within a Jupyter Notebook environment. The simulation result shows that SLEAD outperformed the traditional scheme in-terms of efficient energy utilization and data privacy.
