Problems solved by technology

[0003] Existing mobile storage devices do not have a protection function that prohibits starting, and users can easily make a boot disk to start the host system. For specific industries, such as banking, education, electric power, communication and other systems, it is difficult to use an operating system without security protection. (such as MS-DOS) starting the computer will pose a major threat to data security

Embodiment Construction

[0009] This embodiment provides a solution for the firmware to realize that the USB flash storage device prohibits starting the host system. The so-called prohibition of starting means that the purpose of starting the PC is prohibited through the USB peripheral device startup mode supported by the current PC operating system. USB-HDD (hard disk boot), USB-ZIP, USB-FDD (floppy disk boot) and USB-CDROM (optical drive boot) to boot the PC, considering that the USB flash storage device must be loaded with specific firmware. In order to simulate USB-FDD and USB-CDROM, it is necessary to avoid starting the PC system through these two methods, as long as the USB storage device does not deliberately simulate these two devices, and the USB storage device cannot be made as USB-FDD or USB. - CDROM boot disk.

[0010] For the USB-HDD and USB-ZIP boot methods, users can use ordinary flash storage devices to make boot disks, so this solution mainly realizes from the device level to avoid US...

Abstract

The invention discloses a mobile storage device and method for prohibiting the production of a boot disk. The mobile storage device includes a data storage control unit, and the data storage control unit is provided with firmware. The firmware modifies parameters related to startup to prohibit storage The device is made into a boot disk to boot the host system. The method for prohibiting a mobile storage device from making a boot disk includes: setting a firmware that prohibits startup in the storage device, and when the firmware is powered on, it detects the startup flag at the tail of the logic 0 sector, confirms the startup sector; confirms and modifies MBR startup code, or modify the startup code in the boot sector. The mobile storage device manufactured by the invention has the function of prohibiting the boot disk from being made, and is helpful to improve the data security of the user's host machine for industry users with relatively high data security requirements.

Description

technical field [0001] The present invention relates to the field of mobile storage, in particular to a mobile storage device and method activated by a host system. Background technique [0002] With the continuous development of information technology, information technology is more and more widely used in various fields. It is more and more important to ensure the stability of system operation, especially the security of data storage. Restarting the computer illegally or illegally will affect the Data is quite destructive. In mobile storage devices, especially when flash storage devices are widely used, most computer systems can be started through flash storage devices. The security of data access, prohibiting the ability of flash storage devices to restart the computer system, is becoming more and more important. [0003] Existing mobile storage devices do not have the protection function of prohibiting booting, and users can easily create a bootable disk to boot the hos...
