Physical separated card with single network port

Abstract

A physical isolating card for single network interface is composed of microcontroller chip, network chip connected with said microcontroller chip and network selection chip, IDE circuit, and RJ45 interface connected with said microcontroller chip via transceiver.

Description

technical field [0001] The present invention relates to information technology and network security in the Internet, in particular to a physical isolation card with a single network port. The physical isolation card with a single network port can not only use network resources conveniently and effectively, but also realize real communication between the network and the network. sense of physical isolation. Background technique [0002] In the prior art, physical isolation is the main means adopted by network computer users to prevent hackers from intruding. According to our retrieval, statistics and analysis, we can know that the commonly used physical isolation methods are as follows: [0003] 1. Use 2 computers. But to double the cost and office area, it is inconvenient to use and difficult to promote. [0004] 2. Other various types of security cards, protection cards or software methods. [0005] First of all, the solution based on a hard disk is based on a physical ...
