An equipment isolation device between control safety nets

Abstract

The invention belongs to the technical field of network security, and relates to an isolation device, in particular to an equipment isolation device between control safety nets. The device comprises apublic network device, the network device is arranged in an intranet, the network device controls the network position of the network device through an intranet control unit, the public network device is connected with two external network devices with different security levels, and the public network device is used for controlling the public network device to be connected with a single externalnetwork device; The public network device comprises a power supply protection module, a switching control module and control software. The power supply protection module comprises a power supply unit,a current detection unit and a current signal conversion unit. The power supply unit is used for supplying power to the external network device and is connected with the current detection unit; The power supply unit is used for simultaneously supplying power to the two external network devices connected with the power supply unit; The method and the device are mainly used for isolating and switching the inter-network equipment, and can improve the safe use of the inter-network equipment.

Description

technical field [0001] The invention belongs to the technical field of network security, in particular to a device isolating device between control security networks. Background technique [0002] E-commerce has changed the operation mode of traditional business, greatly improved business efficiency and reduced transaction costs, but such a new business model is also facing a huge security threat. Therefore, in all e-commerce applications, security is considered as the most important factor. At present, the main security risk of e-commerce comes from the client, such as the computer used by the user and the software running on the computer, or the mobile device and the software running on it. Therefore, e-commerce generally adopts identity authentication means with high security strength to confirm the user's identity in e-commerce and prevent counterfeiting and fraud. [0003] There are also technical solutions for network security in the prior art. For example, a Chinese...
