Abstract:

Based on the layered architecture of the Internet of Things (IoT), this paper analyzes the security risks and security needs faced by each layer of the IoT in the era of intelligent interconnection. The layered security architecture and corresponding security measures of the IoT are proposed, forming the overall security idea of IoT, including basic security capability, sensing security, network security, platform security, application security and security protection. In addition, the organization, content and progress of the IoT security standards are studied from both international and domestic aspects, which gives a research direction for IoT security standards and further promotes the building and improvement of intelligent IoT security system.

Key words: IoT security, layered security architecture, security standardization, intelligent interconnection
