Abstract

The invention discloses an Ethernet secret access prevention double-link communication control system and method. The Ethernet secret access prevention double-link communication control system is characterized by comprising a data request side, a data control side and a device side, the data request side sends request data to the data control side after the request data are encrypted, the data control side analyzes the request data and is connected with a device of the assigned device side, the device of the device side receives a connection request of the data control side and sends the connection result to the data request side through the data control side, if connection is successful, the data request side encrypts and sends data to be transmitted to the device side through the data control side or the device side sends data to the data control side, then encrypts the data and sends the data to the data request side. The secure communication link is established through the control link and data link double-link communication and the DES and RSA dual encryption means, the physical device access security and the data transmission security are ensured, and the data secret leakage and the access risk of third-party software can be effectively reduced.

Description

Technical field [0001] The invention relates to the field of Ethernet communication, in particular to an Ethernet anti-theft dual-link communication control system and method. Background technique [0002] In Ethernet communication, in order to save network resources, some clients do not need to connect to all field device servers for a long time, and only connect to the device when needed to view the required information. At the same time, from a security perspective, to ensure the security of device access, Clients are often not allowed to directly access the device, and need to pass through the transfer device to interact with data. In this way, for the device server, its interface objects are directly simplified to face the transfer device instead of more complicated clients, thus ensuring the device The purity of the port data can effectively reduce the risk of virus attacks. [0003] In traditional applications, after the transit device receives the client's connection reque...
