Embodiment Construction

[0040] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0041] In one embodiment, such as figure 1 As shown, a control system is provided, including a master station device 102 and an execution station device 104, wherein the master station device 102 communicates with the execution station device 104 through a network. In this embodiment, when the master station device 102 initiates an action command request, according to the action command request, a first command message is generated and sent to the execution station device 104, and a private key is used to sign the first command message to generate a second command messag...

Abstract

The invention relates to a control system communication method and device based on asymmetric encryption, computer equipment and a storage medium. The method comprises the following steps: when an action command request is initiated, generating a first command message according to the action command request; sending the first command message to an execution station device; signing the first command message by using a private key to generate a second command message; wherein the second command message comprises a first command message and signature information; sending the second command message to an execution station device at preset time intervals; and the execution station device acquires the signature information and the first command message from the second command message, performs signature verification on the signature information by using a public key, and executes an action command of the first command message if the content of the first command message received each time isthe same after the signature verification is passed each time. According to the scheme, the safety of the communication process of the control system can be improved.

Description

technical field [0001] This application relates to the technical field of information security, in particular to a control system communication method, device, computer equipment and storage medium based on asymmetric encryption. Background technique [0002] In the current control system, the master station device communicates with the execution station device. Generally, the master station device sends a multi-frame control command message to the execution station device. After receiving the multi-frame control command message, confirm the content of the multi-frame message, and execute the specified control command action after confirmation. But the traditional control system communication method has the problem of low security. Contents of the invention [0003] Based on this, it is necessary to address the above-mentioned technical problems and provide a control system communication method, device, computer equipment and storage medium based on asymmetric encryption ...
