Multi-channel secure communication framework for wireless IoT (MCSC-WoT): enhancing security in Internet of Things
To address critical security vulnerabilities—including man-in-the-middle, replay, and jamming attacks—as well as high synchronization overhead, excessive energy consumption, and significant latency in resource-constrained IoT/WoT multi-channel communication, this paper proposes a lightweight, multi-channel secure communication framework integrating dynamic frequency hopping with efficient cryptography. The framework co-designs adaptive channel-hopping strategies with AES-128, elliptic-curve cryptography (ECC), and jamming-resilient modulation to achieve low-overhead end-to-end security. Experimental evaluation demonstrates substantial improvements over conventional single-channel encryption and static frequency-hopping schemes: packet delivery ratio increases by 23.6%, average end-to-end latency decreases by 31.4%, energy consumption drops by 27.8%, and bit error rate improves by one order of magnitude across diverse jamming scenarios. These results validate the framework’s effectiveness in balancing security, efficiency, and robustness for constrained IoT/WoT deployments.
