System and method for mobile storage device access control based on power supply strategy

Abstract

The present invention relates to a mobile storage device access control system and method based on a power supply strategy, comprising a computer host module, a USB interface module, a core storage module, a connectivity control module and a password input module; the USB interface module is connected to the core storage via a data line between the module and the computer host module; the USB interface module is connected to the computer host module through the power supply line, and the connectivity control module is connected between the USB interface module and the core storage module through the power supply line; the password input module is connected to the connectivity control module for Used to control the continuity of the power supply circuit. In the present invention, by performing identity authentication on the connectivity control of the power supply circuit, and by controlling the connectivity of the power supply circuit, the encryption, decryption and data are decoupled, and the encryption and decryption of the circuit connectivity can be completed instantly, which improves the user experience level; no need to consider The adaptability of the operating system improves platform compatibility; increases the difficulty of cracking and improves the security of data storage.

Description

technical field [0001] The present invention relates to a mobile storage device access control method, in particular to a mobile storage device access control system and method based on a power supply strategy. Background technique [0002] With the development of global informatization and the continuous improvement of information technology, a large number of confidential documents are stored, exchanged and managed electronically. However, there are prominent security issues in the electronic application and management of secret-related documents. How to effectively prevent leakage of important documents in the application and exchange of important documents has become a key issue in the application of information technology. At present, the commonly used method is to encrypt the data saved on the mobile storage disk, that is, to control the access of the mobile storage device. [0003] Currently, there are three commonly used methods for encrypting data on a removable st...
