USB storage device access control method and system, medium, device and application

Abstract

The invention belongs to the technical field of mobile storage devices, and discloses a USB storage device access control method and system, a medium, a device and an application, the USB storage device access control method comprises a register machine used for negotiating a mode with a user, formulating an encryption mode, managing a secret key, encrypting a USB storage device guide area, and optionally encrypting a data area of a USB storage device; a secret-related machine which can decrypt and read the encrypted USB storage device and cannot read a general computer of a common non-encrypted USB storage device; an analyzer which not only can decrypt and read the encrypted USB storage device, but also can read a universal computer of a common USB storage device. The invention can effectively guarantee that the USB storage device can only be used in a limited range, enhances the safety of the USB storage device and data thereof, is simple to deploy and maintain, supports a multi-operating system platform, and is suitable for individuals and use scenes of different-scale organizations.

Description

technical field [0001] The invention belongs to the technical field of removable storage devices, and in particular relates to a USB storage device access control method, system, medium, device and application. Background technique [0002] At present, as a removable storage device, the USB storage device includes a U disk, a mobile hard disk, an SD card, etc., and is widely used by the public because of its convenience and quickness. Because USB storage devices are easy to cause information loss, its access control strategy has attracted more and more attention. According to the characteristics and functions of the USB storage device, the data on it can be roughly divided into: boot area, file information area, and data area. The boot area stores the relevant information of the USB storage device itself and the boot program. The file information area records the size and location information of each partition of the USB storage device, and reflects the use of each area on...

AI Technical Summary

Problems solved by technology

[0005] (1) The security level of the existing technology is low: the identity verification based on the username and password is easy to be cracked; and the establishment of an access control center also provides the possibility for hackers to intercept data

[0006] (2) The cost of the existing technology is high: identity authentication based on PKI or smart card requires special equipment, resulting in high cost

[0007] (3) The maintenance and deployment of the existing technology is complex: the above methods and strategies require technical personnel to perform complex operations such as equipment distribution and maintenance of the centralized management platform

[0008] (4) Poor compatibility of existing technologies: generally, existing technologies can only support fewer operating systems

[0009] The difficulty of solving the above problems and defects is: the above problems and defects have brought great inconvenience and potential safety hazards to organizations and individuals
