Physically isolated dual-system construction method based on removable storage medium

Abstract

The invention provides a physical isolation dual system construction method based on a removable storage medium, the removable storage medium includes a storage controller module, a storage module, aninterface module, a security module and a wireless communication module, the memory controller module is respectively connected with the memory module, the interface module is connected with the security module. The interface module is connected with the security module and the wireless communication module. The method comprises the following steps: presetting a first operating system including adisk filter driver in the storage module; presetting a second operating system in a local disk of the personal computer; presetting a second operating system in a local disk of the personal computer;after the personal computer is powered on, when the personal computer is connected with the removable storage medium and the PIN code verification passes, the first operating system being allowed tobe loaded and started. The first operating system realizes physical isolation from the second operating system through the disk filter driver.

Description

technical field [0001] The invention relates to the technical field of computer operating systems, in particular to a method for constructing physically isolated dual systems based on mobile storage media. Background technique [0002] At present, government agencies, enterprises and institutions need to install office operating systems and office software on personal computers when they are working, and when dealing with non-office affairs, they need to install ordinary operating systems for personal life and entertainment. If each person is equipped with Two personal computers will increase the cost of work; if an office operating system and an ordinary operating system are installed on one personal computer at the same time, since the existing technology mostly uses local hard disk partitions to realize dual-system logical isolation, when the ordinary operating system is infected After the external virus, it will cause the office operating system and office data, files to...

Problems solved by technology

[0002] At present, government agencies, enterprises and institutions need to install office operating systems and office software on personal computers when they are working, and when dealing with non-office affairs, they need to install ordinary operating systems for personal life and entertainment. If each person is equipped with Two personal computers will increase the cost of work; if an office operating system and an ordinary operating system are installed on one personal computer at the same time, since the existing technology mostly uses local hard disk partitions to realize dual-system logical isolation, when the ordinary operating system is infected After the external virus, it will cause the office operating system and office data, files to be infected with viruses, sensitive files to be stolen, etc., thus affecting the normal safe office

[0003] In addition, with the rapid development of technology and informatization, many government agencies, enterprises and institutions are in urgent need of more convenient, efficient, and safer mobile office services. Office requirements, but the loaded and started office operating system is still associated with the local hard disk of the personal computer, and can be accessed each other, which makes the operating system operating environment of the office system have certain security risks
