A Comprehensive Analysis of Trusted Internet of Things.

As the infrastructure for the development of digital economy, the Internet of Things (IoT) is widely used in electric power, transportation, industry and other fields, bringing digital services to the government, enterprises and individual consumers. At the same time, the IoT also carries more and more production and life information, and its security issues can not be ignored. Besides, some malicious attacks will affect the industry security. Compared with the traditional Internet, the IoT has the characteristics of multi-source, heterogeneity, openness, ubiquity, etc. Due to the defects in the authenticity and reliability of the data itself, the single-dimensional security protection technologies such as data encryption, identity authentication and anomaly detection cannot provide the whole process and system-level trustiness guarantee, which makes it face a more complicated and severe trust crisis. In this paper, the requirements and characteristics of the trusted IoT are firstly introduced. Secondly, the challenges faced by the trusted IoT are analyzed and after the corresponding solutions are proposed. Finally, the development suggestions of the trusted IoT are elaborated.
