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
The write-protect program double shield that the present invention relates to a kind of EWF by Windows XP Embedded operating system itself covering write-protect and USB flash disk controls the outside guard method based on the carry-on operating system of USB flash disk Windows XP Embedded write operating system and USB flash disk.
Background technology
Windows XP Embedded(is also known as Windows Xpe) be a kind of embedded OS, the function of Windows operating system can be provided with Componentized form.Windows Xpe, based on scale-of-two, comprises more than 10000 independently functional module, and therefore developer can select and obtain best-of-breed functionality when management or reduction EMS memory occupation amount in self-defining device reflection.
Windows Xpe operating system can cut randomly according to application needs, and is carved into dish or is contained in USB flash disk, portable hard drive, uses as independent, a complete operating system.User does not need the computer carrying oneself, by being equipped with USB flash disk or the portable hard drive of Windows Xpe system, insert other people PC, just can make the operating system in oneself USB flash disk of the convenient, fast use of user, ensure that the privacy of user and the use habit of program software aspect to greatest extent, be applicable to personnel, financial and accountancy personnel, senior management staff, mobile office personnel etc. that often needs are gone on business.
Windows Xpe system has higher autoprotection function, and its protection is mainly based on EWF resist technology.Enhanced Write Filter (EWF) provides a kind of volume of protecting to prevent the means write.This technology is divided into three kinds of protected modes: hard disk protection pattern, memory protect pattern, memory protect registration table pattern; allow under wherein hard disk protection pattern to write data on protected dish; that is while not input protection instruction, machine can preserve previous amendment after restarting; if memory protect or memory protect registration table pattern; then when there is no input protection instruction; the amendment that current system is done; comprise: mounting software; preserve data etc.; be all temporal cache in internal memory, after system reboot, these amendments can all be lost.
At present, the carry-on operating system of USB flash disk is a lot, but little to the protection of USB flash disk operating system and data.In the face of the attack for system that emerges in an endless stream, only rely on the protected mode of Windows Xpe system self, can not the safety of available protecting system.Meanwhile, the feature of the plug and play that USB flash disk has, makes the data in USB flash disk more easily be subject to invasion and the destruction of virus.Therefore, how to ensure that the safety of the carry-on operating system of USB flash disk is a problem demanding prompt solution.
Summary of the invention
The object of the invention is to overcome lacking and single deficiency and provide a kind of guard method of the Windows XP Embedded carry-on operating system based on USB flash disk to the operating system of USB flash disk and the protected mode of data in prior art, the write-protect program double shield covering write-protect and USB flash disk by the EWF of Windows XP Embedded operating system itself protects the safety of data in USB flash disk Windows XP Embedded operating system and USB flash disk.
Technical scheme of the present invention is: a kind of guard method of the carry-on operating system of Windows XP Embedded based on USB flash disk; by by Windows XP Embedded operating system installation in USB flash disk; system as movement uses; it is characterized in that: the write-protect program covering write-protect and USB flash disk by the EWF of Windows XP Embedded operating system itself forms double shield and controls the outside write to operating system and USB flash disk, and its realization comprises two kinds of situations:
1) do not change USB flash disk data or do not preserve alter operation, implementation step comprises:
Step 1.1, the BIOS of terminal is set, terminal is guided from USB port and starts;
Step 1.2, insertion are provided with the USB flash disk of Windows Xpe operating system and USB flash disk write-protect program;
Step 1.3, operating system start from USB flash disk, and the EWF of system itself performs write protection, and the write-protect program of USB flash disk is run automatically, and double write protection ensures operating system and USB flash disk data security;
Step 1.4, user operate in operation system interface, and all operations can only write buffer memory, cannot be saved in USB flash disk;
Step 1.5, reboot operation system, all operations record disappear, System recover to before version;
2) write data to USB flash disk and preserve the data of write, implementation step comprises:
Step 2.1, the BIOS of terminal is set, terminal is guided from USB port and starts;
Step 2.2, insertion are provided with the USB flash disk of Windows Xpe operating system and USB flash disk write-protect program;
Step 2.3, by USB flash disk write-protect program, send shutdown command, close the write-protect program of USB flash disk, USB flash disk is in can write state;
Step 2.4, by EWF manager application, input write protection order, system is in can write state;
Step 2.5, user carry out writing or changing operating and submitting in operation system interface;
The data that user submits to by step 2.6, system are stored in USB flash disk, and reboot operation system, the data of user's write are saved.
Described USB flash disk is have the read-only function of physics and carry out mutual special USB flash disk by order and external unit; When USB flash disk uses as movable storage device, by the control of USB flash disk write-protect program, USB flash disk is in a read states, when needing to carry out the storage of data or modify to data, then needs to close USB flash disk write-protect program by order, USB flash disk is in and can writes state.
The invention has the beneficial effects as follows: the present invention is by the writing protection function of Windows Xpe operating system itself and in conjunction with the Write-protection method of USB flash disk; by double protection measure; data on the protection disk especially integrality of operating system and safety, avoids the invasion of virus, network attack etc.Simultaneously, by Windows Xpe system is loaded in USB flash disk, as one complete can operating system, user can carry with, computer need not be carried and this system is inserted into the process carrying out information that any PC just can be relieved, realize real mobile security office.
