Internet of Things security terminal and security control method thereof

Abstract

The invention provides an Internet of Things safety terminal and a safety control method thereof. The Internet of Things security terminal comprises a security microcontroller, the safety microcontroller comprises a central processing unit, a service storage area in which a service system for realizing service control is stored, and a security storage area, wherein only the central processing unithas authority to access the secure storage area, a security control system is stored in the security storage area, the management authority of the security control system is higher than that of the service system, and the central processing unit can call the security control system to perform security check on the service system, so that the service system is prevented from being maliciously tampered or damaged and the like, and corresponding security control can be performed when the security check fails; therefore, safety control on the terminal side of the Internet of Things is realized, and the safety of the Internet of Things can be effectively improved.

Description

technical field [0001] The present invention relates to the field of Internet of Things (The Internet of Things, IOT), in particular to an Internet of Things security terminal and a security control method thereof. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important development stage in the "informationization" era. A series of Internet of Things such as smart factories, smart homes, and smart transportation have gradually entered people's lives with the development of communication technology. work and life. [0003] The Internet of Things realizes the ubiquitous connection between things and things and between things and people through various possible network accesses, and realizes the intelligent perception, identification and management of objects and processes. The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks,...

AI Technical Summary

Problems solved by technology

The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc. It allows all ordinary physical objects that can be independently addressed to form an interconnected network; for the general Internet of Things architecture, please refer to figure 1 As shown, including the corresponding Internet of Things terminals in the external network, firewall and internal network; this kind of connection between things brings innovation and also brings security risks

In the current IoT architecture, firewalls are used to isolate a safe physical environment at the border, and the security control in the intranet (that is, the isolated area) is blank. When the firewall is breached or the attacker passes through other When the Internet of Things terminals in the intranet are maliciously tampered with or implanted, the current method of defense through the firewall is useless
