Data encryption transmission method and device, terminal equipment and storage medium

Abstract

The invention discloses a data encryption transmission method and device, terminal equipment and a storage medium, the data encryption transmission method is applied to a remote system in an industrial production system, the industrial production system further comprises a headquarters system, and data in a remote control system in the remote system is acquired and transmitted to the headquarters system. Converting the data into a network plaintext message; encrypting the network plaintext message through a data security transmission module in the remote system to obtain an encrypted message; and sending the encrypted message to the headquarters system, so that a security gateway in the headquarters system decrypts the encrypted message to obtain the network plaintext message, and sending the network plaintext message to a control center in the headquarters system. According to the invention, the security problem of data transmission between the remote data transmission equipment and the control center is solved.

Description

Technical field [0001] The present invention relates to the field of information security, and more particularly to a data encryption transmission method, a device, a terminal device, and a storage medium. Background technique [0002] In industrial environments such as intelligent oil and gas fields, smart grids, environmental testing, tens of thousands of remote control systems are applied, and communication between these RTU and control centers rely on remote data transfer. Device (DATA TRANSFER Unit, DTU). The main function of the DTU is to convert the serial data of the remote control system into IP (Internet Protocol, Internet Convection Protocol) packets, communicating with the control center with wireless way, and reach the monitoring and control of remote control systems. Today, the Internet is growing, and the use of DTU is also more wide. It provides assistance for the information and industrial integration between industry and industry. [0003] The communication of t...

Problems solved by technology

[0003] The communication between the DTU products and the control center currently on the market is carried out in plain text, resulting in the instructions issued by the control center to the RTU and the data reported by the RTU to the control center are all exposed to the Internet. Once the attacker hijacks these data and If it is modified, the remote control system will execute wrong or abnormal instructions, or the control center will obtain wrong remote control system data, which will directly affect the safety of the industrial production system

[0004] Therefore, it is necessary to propose a solution to the data transmission security problem between the data transmission equipment and the control center
