Abstract

The invention relates to a data transmission security control method and device, computer equipment and an Internet of Things system. The data transmission security control method applied to a targetnetwork node terminal comprises the steps of obtaining a dynamic code sent by a server; generating a key seed according to the dynamic code, the configuration information of the target network node terminal and a key seed generation algorithm; inputting the key seed into a symmetric key generator, and obtaining a first key generated by the symmetric key generator; and performing data encryption ordecryption by adopting the first key. A dynamically changing key seed is obtained through dynamic and static combination, so that the data transmission security of the target network node terminal isimproved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a data transmission security control method and device, computer equipment, and an Internet of Things system. Background technique [0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art. [0003] The AIoT (Artificial Internet of Thing) is booming, and the number of smart terminals (Smart Terminal) is increasing sharply, with great security risks and a low proportion of security links in the IoT industry chain. The Internet of Things business penetrates into many industries and affects people's lives in all aspects. The corresponding security issues will also pose serious threats, even including life and property safety. Terminal security is getting more and more attention. Among them, data transmission security in the communication process is a key link in terminal s...
