Yao Hu, Jinglong Chen, Bibo Tu · IEEE Transactions on Industrial Informatics · 2025
Harnessingthe data processing and communication capabilities of the Internet of Things (IoT), smart grids can seamlessly share power information across wired and wireless networks, enhancing the grid's reliability, stability, sustainability, and energy efficiency. Since smart meters' communication in the IoT network is carried out on the public channel, there is significant uncertainty about the authenticity of the transmitted electricity data and the security of the smart meter keys. Existing solutions cannot well-handle the above security issues. Therefore, in this article, an efficient authentication scheme with key leakage-resistance, signing key leakage-resistant authentication (SKLRA), for the IoT-enabled smart grid is proposed for IoT-integrated smart grids. The SKLRA scheme is designed to overcome the performance shortcomings and security limitations found in traditional certificateless key-insulated signature mechanisms and certificateless signature approaches that do not utilize random oracles, particularly for smart grid applications. We also provide a rigorous security analysis alongside experimental evaluations to demonstrate the robustness and practical viability of the SKLRA scheme in real-world applications.
