Mobile storage device access control system and method based on power supply strategy

Abstract

The invention relates to a mobile storage device access control system and method based on a power supply strategy. The system comprises a computer host module, a USB interface module, a core storagemodule, a connectivity control module and a password input module. The USB interface module is connected between the core storage module and the computer host module through a data line; the USB interface module is connected with the computer host module through a power supply line, and the connectivity control module is connected between the USB interface module and the core storage module through a power supply line. The password input module is connected to the connectivity control module and is used for controlling the connectivity of the power supply circuit. According to the invention, identity authentication is carried out on connectivity control of the power supply circuit, and the connectivity of the power supply circuit is controlled, so that encryption and decryption are uncooked with data, and circuit connectivity encryption and decryption can be instantly completed, and the user experience level is improved; the adaptability of an operating system does not need to be considered, and the platform compatibility is improved; therefore, the cracking difficulty is improved, and the data storage security is improved.

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...
