| 摘 要: 针对当前物联网数据量庞大且数据之间孤立,以及物联网可信访问服务管理中交易不透明和易受攻击等问题,提出了基于区块链的物联网可信访问控制研究,将区块链技术应用到物联网的访问控制中,利用区块链的去中心化特性结合物联网访问控制技术,设计了物联网可信访问控制模型。通过模拟实验显示,物联网可信访问控制模型能够有效量化信任度、有效检测到物联网访问攻击行为,在整个访问控制中能够确保数据不被篡改,在每500次访问增量下的攻击检测率可提升约1.77百分点,具有较高的实用性。 |

| Abstract: In response to the current issues of massive data volume and isolation between data in the Internet of Things (IoT), as well as the lack of transparency and vulnerability to attacks in the management of trusted access services in IoT, this paper proposes a research on trusted access control for the Internet of Things based on blockchain. By applying blockchain technology to access control in the Internet of Things, the study combines the decentralized nature of blockchain with IoT access control technology to design a trusted access control model for the Internet of Things. Simulation experiments demonstrate that the IoT trusted access control model can effectively quantify trustworthiness, detect IoT access attack behaviors, and protect the data from being tampered throughout the access control process. The proposed model improves the attack detection rate by approximately 1.77 percentage points every 500 incremental visits, indicating its high practicality. |
