Embodiment 1

[0029] This embodiment discloses a data encryption bus adaptive remote system upgrade method for industrial equipment, such as figure 1 As shown, the method includes: connecting the smart device to the bus network owned by the industrial equipment; after the smart device is powered on, connects to the remote server, connects the transmission link through network technology, and the remote server receives the networking request of the smart device Finally, after establishing the transmission link and waiting for the connection to be completed, listen to the instructions of the remote server; after the remote server sends the data, it performs the first layer of encryption of the software data, and the first layer of encryption is the conversion of the software data to be transmitted ; After the binary conversion of the data is completed, the data is encrypted by the second layer, wherein, the encrypted data of the second layer includes network IP and port; the data after the sec...

Embodiment 2

[0050] This embodiment discloses a data encryption bus adaptive remote upgrade system for industrial equipment, which at least includes smart devices and remote servers. The smart devices are connected to the bus network of industrial devices. After the smart devices are powered on, they connect to the remote server. The transmission link is connected through network technology. After the remote server receives the networking request of the smart device, it establishes the transmission link and waits for the connection to be completed, then monitors the instructions of the remote server; after the remote server sends the data, it performs the first layer of encryption of the software data. The first layer of encryption is the conversion of the software data to be transmitted; after the conversion of the data is completed, the second layer of encryption is carried out to the data, wherein, the network IP and port are included; after the second layer of encryption The final data ...

Abstract

The invention relates to a secure communication method based on an industrial data bus, and the method at least comprises the steps: carrying out the first-layer encryption of software data after a remote server issues data, and carrying out the system conversion of the software data to be transmitted; sequentially dividing data subjected to system conversion into two groups of digits with equal digits, if the converted data is an odd number of digits, adding zero to the first digit and then splitting, splitting according to a digit sequence or splitting at an interval, arranging one or two groups of the two groups of digits with equal digits after splitting in an inverted sequence, and then transmitting; adding a three-bit binary character before each piece of transmission data to represent a data processing mode through which the data passes; and then performing second-layer encryption on the data, wherein the data after the second-layer encryption comprises a network IP and a port.

Description

[0001] The present invention is a divisional application with the application number 202011005123.6, the application date is September 22, 2020, the application type is invention, and the application name is a data encryption bus adaptive remote system upgrade method for industrial equipment. technical field [0002] The invention relates to the technical field of communication, in particular to a method for secure communication based on an industrial data bus. Background technique [0003] Industrial equipment plays an increasingly important role in the national economic system. It has the excellent characteristics of long service life, reliable quality and wear resistance. Once it is put into normal use, it is often time-consuming and laborious to upgrade its system. From the dismantling of the complete equipment, the preparation of upgrade materials on site, and the verification of the upgrade system, more importantly, in the preparation of the project, the technical perso...
