Embodiment Construction

[0084] A data parallel encrypted communication system based on Modbus protocol, including a data acquisition site and a central monitoring system. The above-mentioned data acquisition site includes a site configuration module, a data acquisition module, an improved SM4 parallel encryption module and a data transmission module. The data acquisition module collects the equipment operation information of the data acquisition site according to the information in the configuration information table, and the collected data is plaintext data. The SM4 parallel encryption module uses the GPU-based dynamically selected SM4 parallel encryption method to perform encryption operations on plaintext data to obtain ciphertext data. The data transmission module sends and processes encrypted ciphertext data. The above central monitoring system includes a data receiving module, an improved SM4 parallel decryption module and a data display monitoring module. The data receiving module receives a...

Abstract

The invention discloses a data parallel encryption communication method and system based on a Modbus protocol. The communication system comprises: a data collection site and a central monitoring system; the data collection site comprises a site configuration module, a data collection module, a modified SM4 parallel encryption module and a data transmission module; the central monitoring system comprises a data receiving module, a modified SM4 parallel description module and a data display monitoring module. In application of the communication system of the invention, the transmission security of industrial data is improved; the encryption speed of the real industrial data is improved; therefore the encryption processing delay is reduced; and the system has an offline reconnection mechanism, therefore, the device is monitored discontinuously.

Description

technical field [0001] The invention belongs to the field of industrial monitoring and relates to data encryption and decryption parallel processing, in particular to a data parallel encryption communication method and system based on Modbus protocol. Background technique [0002] With the development of the Internet of Things, the demand for centralized data monitoring by connecting devices produced by different manufacturers into an industrial network is increasing, and the real-time requirements for industrial network transmission are also increasing. [0003] The Modbus bus protocol has become an industrial standard because of its open protocol, easy implementation and high reliability, and has also been supported by various equipment manufacturers. Modbus communication adopts the master-slave communication mode, the master station sends data request information, and the slave station can send data to the master station to respond to the request after receiving the corre...
