Secure Data Transmission in Wireless Sensor Networks Using Hybrid Encryption

Abstract

In many industries today, including healthcare monitoring, environmental monitoring, and intelligent infrastructure, wireless sensor networks (WSNs) serve as a crucial base for cutting-edge applications. However, their openness and lack of resources make them especially susceptible to security risks like illegal access, data manipulation, and eavesdropping. In these networks, trust in systems that frequently work in highly regulated and mission-critical contexts depends on safe data transmission, which is more than just a technological need. The hybrid encryption scheme, which combines the speed of symmetric cryptography with the security of asymmetric methods, is the subject of this study. The suggested model seeks to strike a reasonable balance between optimum security and maximum resource usage by taking advantage of the strengths of both. The study examines the impact of hybrid encryption on data integrity, transmission latency, and energy efficiency in WSNs through simulation and performance analysis. The main goal is to develop a solution that is lightweight and safe, enabling wireless sensor networks to run continuously even in harsh real-world environments.
