Abstract
With the rapid development of Internet of Things (IoT) technology, a massive number of devices are connecting to networks, generating an enormous volume of data. Traditional database security mechanisms struggle to meet the security requirements in IoT environments. To address this issue, this paper constructs a database security model specifically designed for IoT applications, aiming to solve data storage and access security problems under IoT conditions, ensuring data integrity, confidentiality, and availability. By analyzing the characteristics of IoT architecture and the inadequacies of existing database security systems, a security model combining attribute-based encryption with fine-grained access control is proposed. This model leverages attribute-based encryption for secure data storage and integrates access control policies to precisely manage user permissions. In terms of experimental validation, a prototype system was designed and implemented, and the model's performance was tested across multiple typical IoT application scenarios. The results demonstrate that the proposed model not only effectively resists various types of attacks but also significantly improves processing efficiency compared to traditional solutions. The innovation lies in the deep integration of attribute-based encryption with access control, ensuring both data security and system performance. This provides a new approach to IoT database security. The primary contribution is offering a practical technical solution for database security protection in IoT environments, which holds significant theoretical and practical value for safeguarding IoT data security.
