Internet of Things security authentication method and system

Abstract

The embodiment of the invention discloses an Internet of Things security authentication method and system. The system comprises terminal equipment and a security authentication module. The security authentication module is in communication connection with the terminal equipment, and when the security authentication module receives a security authentication request sent by the terminal equipment, security authentication can be carried out on the terminal equipment according to the security authentication request, and a security authentication result is sent to the terminal equipment. The security authentication module does not belong to the internal module of the terminal equipment. Therefore, based on the system, the cost of the terminal equipment is not increased, and the defects that inthe prior art, when safety authentication is conducted on the Internet of Things, the safety of a software authentication mode is poor, and the cost is increased due to the fact that the internal structure of the terminal equipment needs to be changed in a hardware authentication mode can be overcome at the same time.

Description

technical field [0001] The present application relates to the technical field of security authentication, in particular to a method and system for security authentication of the Internet of Things. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. Its English name is: "Internet of things (IoT)". As the name suggests, the Internet of Things is the Internet of things connected. This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; Exchange and communication, that is, things are closely related. The Internet of Things is widely used in the integration of networks through communication perception technologies such as intelligent perception, identification technology and pervasive computing. Therefore, it is call...

Problems solved by technology

[0006] The disadvantage of software authentication is mainly low security. The highest security level of software authentication is EAL2+. Its core authentication algorithm is implemented by software. Key data and key information are only stored in the software storage area, and the existing operating system and software There are many security holes

[0007] Although the existing hardware authentication scheme has high security, since the terminal equipment needs to be separately loaded with a special security hardware, the issue, installation and use of the hardware modules of the terminal equipment require additional management, and the original Re-design the layout of components in some terminal equipment products, so as to design the security hardware in the terminal equipment

In this way, the existing hardware authentication scheme has the following disadvantages: a separate hardware authentication module needs to be added to the original terminal equipment, which will increase a lot of extra costs
