Internet of Things terminal device and method for establishing TCP connection with remote management platform

Abstract

The invention provides an Internet of Things terminal device and a method for establishing TCP connection with a remote management platform. TCP connection is established based on the fact that terminal device serves as a client and a remote management platform serves as a server, and remote configuration of the Internet of Things terminal device is completed. The configuration management of the Internet of Things system on the terminal device is the characteristic of a low-frequency event. The configuration port of the terminal device is closed daily, to reject external remote connection. Only when remote connection with a server preset by terminal device is started, a client server mode is adopted, the terminal device serves as a client, a remote management platform serves as a server toestablish TCP connection, and remote configuration of the terminal device is completed, that is, a configuration port of the terminal device initiates access to the configuration port of the management platform, and connection is established. The difficulty that an attacker invades the configuration management module of the Internet of Things terminal device can be increased, and the safety of the connected TCP connection is ensured.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of network security protection, in particular to an Internet of Things terminal device and a method for establishing a TCP connection with a remote management platform. [0003] 【Background technique】 [0004] There is no specific definition of the Internet of Things, but whether it is academia, industry, or government management departments, there is basically the following consensus: the basic architecture of the Internet of Things includes three logical layers, namely, the perception layer, the network transmission layer, and the processing and application layer. The perception layer is composed of a large number of intelligent terminal devices, and its function is to collect the surrounding physical environment information and upload the perception data; the transmission layer is actually a transmission network with the Internet as the core, and its function is to transmit these perception data to...

Problems solved by technology

But this method also has potential security risks, the main reason is that the terminal device must keep the TCP endpoint open at all times to accept access from the management platform and establish a connection

From the perspective of cost, terminal devices often have limited computing resources, and it is difficult to establish a security mechanism with sufficient strength to identify the legitimacy of communication objects.
