Protection method based on Windows XP Embedded carry-on operation system of U disk (USB (universal serial bus) flash disk)

Abstract

The invention relates to a protection method based on the Windows XP Embedded carry-on operation system of a U disk (USB (universal serial bus) flash disk), which is used for controlling the write-in of the outside to the operation system and the U disk via the own EWF (Enhanced Write Filter) covering write protection of the Windows XP Embedded operation system and the write-protection program of the U disk, wherein when data need to be written in the U disk or data in the U disk need to be changed, an opening command is transmitted via the write-protection program of the U disk, and the write-protection program is closed so as to conduct a write-in operation; conversely, the U disk is defaulted to be in a read-only state. According to the protection method, the Windows XP Embedded operation system of the U disk and the data in the U disk are protected via double guarantee, thus preventing the write-in of the outside to the operation system and the U disc, and avoiding the intrusions of virus, network attack and the like.

Description

technical field [0001] The present invention relates to a protection method based on the U-disk Windows XP Embedded portable operating system that controls external writing to the operating system and the U-disk through the double protection of the EWF overwrite protection of the Windows XP Embedded operating system itself and the write-protection program of the U-disk. . Background technique [0002] Windows XP Embedded (also known as Windows Xpe) is an embedded operating system that can provide the functions of the Windows operating system in a componentized form. Windows XPe is binary-based and contains more than 10,000 individual functional components, so developers can choose and get the best features when managing or reducing the memory footprint in custom device images. [0003] The Windows Xpe operating system can be arbitrarily cut according to application needs, and be carved into a disk or installed in a U disk or a mobile hard disk, and used as a separate and co...
