Abstract

The invention, which belongs to the information security field, discloses an access control method of a mobile memory, the mobile memory and a system. The method comprises the following steps that: a mobile memory obtains a user certificate from user certificates stored in a certificate storage device through a certificate read-write interface; the mobile memory uses a root certificate stored in advance to carry out authentication on the obtained user certificate; and after the authentication is done successfully, the mobile memory receives a file information browsing request sent by a file information display device that is connected with the mobile memory and extracts file information that is corresponded to the file information browsing request; and the extracted file information is sent to the file information display device to carry out displaying. According to the method provided in the invention, a poor security problem of access control of a mobile storage device in the prior art can be solved, wherein the problem is caused by employing a static password to carried out user identity authentication.

Description

technical field [0001] The invention relates to the field of information security, in particular to an access control method of a mobile memory, a mobile memory and a system. Background technique [0002] With the rapid popularization of mobile storage, especially mobile storage with USB as the interface (hereinafter referred to as U disk), the security of files stored in the U disk is increasingly concerned. [0003] In order to enhance the security of the USB flash disk, the secure USB flash disk capable of controlling the file access operation of the USB flash disk has been gradually applied to fields such as military affairs, finance, and commerce. The basic principle of access control of the secure USB flash drive is that before the user accesses the files in the secure USB flash drive, the user needs to send an authentication password (hereinafter referred to as the password) to the secure USB flash drive through the computer terminal, and the secure USB flash drive au...
