Abstract

A safe data transmission method of an industrial sensor network system belongs to the technical field of data transmission. The invention aims to solve the problems of complex implementation process and high technical difficulty of the existing safe transmission method of sensor data. The method comprises the steps that random signals are used for driving to generate random numbers, and shieldingdata are obtained through calculation; sequentially superposing the acquired sensor measurement data on different channels of the shielding data to obtain encrypted data for network transmission; andrestoring the received encrypted data through the decryption matrix at the receiving end to obtain restored data. According to the method, the data security transmission problem and the reliability detection problem of the industrial sensor network system are solved under the unified design framework, and the cost of security design and security modules can be reduced to the maximum extent.

Description

technical field [0001] The invention relates to a data security transmission method for an industrial sensor network system, and belongs to the technical field of data transmission. Background technique [0002] Under the background of rapid development and continuous innovation of computer network technology, communication technology, control and system technology, the deep integration of industrialization and informatization has become an extremely important research topic, which has great demands in all aspects of production and life. [0003] In the context of new industries, the safe and reliable design of "cyber-physical systems" that combine traditional information technology and automatic control technology has become the core of current innovative research. Among them, there are huge security risks in the data transmission and sharing between industrial sensor networks and other production equipment. In fact, there have been many actual industrial network intrusion...
