A Secure Clock Synchronization Scheme in WSNs Adapted for IoT-based Applications

This research investigates the intersection of secure clock synchronization and cryptography in the Internet of Things (IoT) context. Cryptography is employed to address challenges in achieving consensus on a system clock among nodes, even in the presence of malicious entities attempting to disrupt synchronization. The paper introduces an innovative synchronization scheme with two main components: a lightweight linear encryption method to secure clock messages against specific attacks and a simple consensus algorithm to compute the synchronized system clock. This scheme, designed for Wireless Sensor Networks (WSNs), aims to overcome issues such as high energy consumption and susceptibility to attacks found in existing synchronization techniques. The study’s results demonstrate the proposed scheme’s efficacy in enhancing secure clock synchronization within IoT environments.
