Security Architecture of the Internet of Things Oriented to Perceptual Layer

The Internet of Things (IoT) is a ubiquitous Internet-based network. However, the IoT exhibits characteristics that pose considerable risks: inherent openness, heterogeneity, and terminal vulnerability. Thus, a new type of architecture must be established to ensure security. The new architecture should aim to improve the efficiency, reliability, and controllability of the entire security system. It should also cover most security technologies and ensure thorough compatibility of various security mechanisms. Therefore, this study investigates all possible attacks and security threats to the IoT and proposes related security technologies. This study presents a design of a highly refined security subject and universal two-dimensional security architecture integrated with related safety technologies.
