System, method and device for near-end maintenance authentication in Internet of Things

Abstract

The invention discloses a system, a method and a device for near-end maintenance authentication in the Internet of Things. The system for establishing near-end maintenance authentication in the Internet of Things comprises a remote security center, a near-end maintenance terminal and maintained equipment, when the maintained equipment is online, the maintained equipment interacts with the remote security center, and the remote security center manages near-end authentication information of the maintained equipment; and when the maintained equipment is not online, the near-end maintenance terminal performs bidirectional authentication with the maintained equipment based on the near-end authentication information. Thus, the maintained equipment is timely synchronized with the remote security center when being online, the remote security center sets and manages the near-end authentication information, and authentication between the near-end maintenance terminal and the maintained equipment is realized based on the near-end authentication information before near-end maintenance is required, so that when the maintained equipment is maintained at the near end, safe and reliable security authentication is carried out.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a system, method and device for near-end maintenance authentication in the Internet of Things. Background technique [0002] With the development of computer technology and Internet network technology, the Internet of Things has emerged. The Internet of Things (IoT, Internet of things) is the "Internet that connects everything". It is an extended and expanded network based on the Internet. Anywhere, the interconnection of people, machines and things. [0003] When authenticating the maintained device in the Internet of Things, the shared key method is often used, that is, the single-factor authentication method of user name + key, and the maintenance device authenticates it. There is a possibility that the terminal's near-end attack decompilation will be cracked. Specifically, when performing maintenance on the equipment to be maintained, local maintenance is often used, tha...

Problems solved by technology

Furthermore, the equipment to be maintained is often in a state of communication interruption, unable to access the network side of the Internet of Things, and lacks a second authentication channel to authenticate the near-end maintenance equipment, resulting in unreliable authentication
