Multi-channel encrypted remote maintenance system based on industrial control network

Abstract

The invention discloses a multi-channel encryption remote maintenance system based on an industrial control network, including a network control module, a single-channel encryption module, a remote monitoring maintenance module and a channel multiplexing module. Before formal communication, any communication channel in the industrial control network is first selected to encrypt and transmit the transmission content in the channel, and then the encrypted communication channel is multi-channel multiplexed, and the encrypted communication channel Multiplex to other unencrypted channels to realize multi-channel encryption in the industrial control network. During the process of human-computer interaction, system controllers can remotely monitor and maintain the system, and monitor system abnormalities in real time. The invention provides a remote maintenance system with high safety, strong operability and simple operation, and provides people with a good reference for remote monitoring of industrial control networks.

Description

technical field [0001] The invention relates to the field of industrial communication security, in particular to a multi-channel encrypted remote maintenance system based on an industrial control network. Background technique [0002] With the continuous development of computer technology and communication technology, in the traditional industrial field, it is gradually developing towards the direction of networking. More and more applications combining industrial systems and computers provide many conveniences for industrial management. With the industrial control network The increase and wide coverage, the equipment that needs to be maintained is also increasing, which increases the difficulty of system maintenance. In the existing industrial control network maintenance system, people usually use the method of remote monitoring and maintenance to monitor and maintain the industrial communication network. monitoring and maintenance, but the existing monitoring and maintenan...

Problems solved by technology

[0003] 1. In the prior art, people usually encrypt the communication line by means of password setting, identity verification, etc. Although this encryption method has certain security, it cannot avoid the problems of identity fraud and password theft, and the security of the system cannot be avoided. The security is not high enough, prone to information leakage and other problems;

[0004] 2. In the current system, there is only one connection mode between each module or each device. When the connection fails, it is easy to cause problems such as interruption of system communication, which will lead to a series of problems such as information loss and information blocking channels;

[0005] 3. In the existing technology, when a certain equipment in the system fails, the failure can only be repaired and repaired manually. If the repair is not timely, it will have a negative impact on the normal operation of the system;

[0006] 4. The existing method of encrypting the system is usually to encrypt the transmission data or encrypt the channel at the same time. The complexity of the encryption process increases the burden on the system operation and cannot achieve the optimal effect of the system.
