Abstract
The rapid development of the Internet of Things (IoT) has made interconnectivity among devices commonplace, yet it has also introduced significant security challenges. Device authentication and key management are critical components for ensuring IoT security. This study focuses on addressing the issues of device authentication and key management in IoT environments, aiming to construct an efficient, secure, and adaptable mechanism. To this end, we propose a method that integrates identity-based group signature schemes with verifiable secret sharing technology for device authentication and key management. This approach not only enables effective verification of device identities, ensuring that only legitimate devices can access the network, but also facilitates secure key distribution and updates through verifiable secret sharing, effectively mitigating the risk of key leakage. Simulation experiments conducted in various typical IoT application scenarios demonstrate that the proposed method achieves low computational overhead and communication costs while maintaining high security, thereby realizing efficient device authentication and key management. By innovatively combining these two technologies for application in the IoT domain, this solution offers new insights into resolving the challenges of device authentication and key management in IoT systems, contributing positively to the advancement of IoT security.
