Abstract
The design and analysis of Internet of Things (IoT) security protocols focus on addressing the increasingly complex cybersecurity challenges in IoT environments. With the surge in the number of IoT devices and the continuous expansion of application scenarios, traditional security mechanisms struggle to meet the demands of low power consumption, high concurrency, and heterogeneity. This study aims to construct a security protocol fr amework suitable for resource-constrained environments, ensuring confidentiality, integrity, and availability of data transmission. By introducing lightweight encryption algorithms and optimized authentication mechanisms, a distributed authentication scheme based on elliptic curve cryptography is proposed. This scheme significantly reduces computational overhead while maintaining security. Formal verification methods are employed to model and analyze the protocol, and the SPIN model checker tool is utilized to validate its correctness and robustness. Experimental results demonstrate that the designed security protocol exhibits superior performance in various typical IoT scenarios, particularly in low-power wide-area networks. Compared with existing solutions, the proposed protocol not only enhances communication efficiency but also strengthens resistance against common threats such as replay attacks and man-in-the-middle attacks, providing a solid theoretical foundation and technical guarantee for the secure and stable operation of IoT systems. This research offers new insights and directions for the development of future IoT security architectures.
