Internet of Things Security Architecture
May 16, 2018

Internet of Things Security Architecture


The security of the Internet of Things like the security of the Internet, will always be a topic of widespread concern. Since the objects connected to and processed by the Internet of Things are mainly machines or objects and related data, its “ownership” feature leads to higher information security requirements for the Internet of Things than to the Internet, which deals with “text”, and to “Privacy”, the requirements for protection are also higher (as indicated in the ITU Internet of Things report), as well as trust issues, including "anti-counterfeiting" and DoS (Denial of Services) (ie, the use of fake end-replacement (eavesdropping, etc.) Means to invade the system, causing real ends to become unusable, etc.), therefore, many people have called for paying special attention to the security of the Internet of Things.


The security of IoT systems is basically the same as that of general IT systems. There are eight main criteria: read control, privacy protection, user authentication, non-repudiation, data confidentiality, communication layer security, data integrity, and availability at any time. The first four are mainly at the application layer of the Internet of Things DCM three-tier architecture, and the last four are mainly at the transport layer and the sensing layer. The "privacy" and "reliability" (data integrity and confidentiality) issues are particular concern in the Internet of Things system. If we carefully analyze the various aspects of the architecture of the Internet of Things system, we will find that the existing security system can basically meet the needs of Internet of Things applications, especially in its primary and intermediate stages of development.
