Design of Industrial Control Data Security Transmission System Based on Blockchain Technology
Abstract：The currently designed industrial control data secure transmission system has a low encryption rate, resulting in poor encryption process stability. In order to solve the above problems, a new industrial control data secure transmission system is designed based on blockchain technology. The system hardware adopts the embedded Kirin 990 processor, which is composed of a single-chip microcomputer, memory and expansion circuit, and adopts a dual-frequency JJSH-9 transmitter to replace the traditional transmitter. The two ends of the transmitter are equipped with dual-frequency GPS receiving antennas to complete the transmission and reception of industrial control data, and configure a PLC multi-channel guide rail controller. Use an asymmetric encryption algorithm to encrypt the industrial control data that needs to be transmitted to ensure data security. The asymmetric encryption algorithm is composed of two parts: data encryption and decryption. The algorithm automatically generates a key pair through the key space sequence, and can generate a decryption key to complete the decryption. The experimental results show that the designed industrial control data security transmission system based on blockchain technology uses the encryption rate of industrial control data security transmission and the stability of data transmission to achieve the expected set goals and can be put into use.
