ENHANCED BIT DISAGREEMENT FOR THE INTERNET OF THINGS USING PHYSICAL LAYER KEY GENERATION BASED ON MODIFIED WINDOWS

Abstract

The Internet of Things (IoT) is a paradigm where myriad devices in households, vehicles, and industrial settings interconnect. The proliferation of interconnected devices poses security challenges, making IoT networks susceptible to eavesdropping and replay attacks. To address this issue, a lightweight key generation scheme is proposed in this article, focusing on enhancing quantization and information reconciliation. The proposed approach employs a modified window along with discrete wavelet transform (DWT) for key generation. To validate the effectiveness of the proposed approach, simulations are conducted for varying numbers of device nodes in both indoor and outdoor scenarios. The evaluation of results suggests that the proposed algorithm surpasses existing key generation algorithms in terms of performance and reliability. Furthermore, comparative analyses demonstrate the superior performance of our method compared to other relevant schemes.
