U disk security encryption management method

Abstract

The invention discloses a U disk security encryption management method. The method comprises the following steps of 1) establishing a connection; 2) performing login; 3) performing general region operation; 4) performing encrypted region operation; 5) performing transmission file security management; 6) performing storage file security management; and 7) performing hardware environment security management. According to the U disk security encryption management method, a general region is arranged in a U disk, so that the U disk is used as a general U disk; an encrypted region is arranged in the U disk, so that the U disk is used as an encrypted U disk; the encrypted region is hidden when not in use; when the encrypted region needs to be used, the login is performed as an administrator through a login display program set in the encrypted region, so that files of the encrypted region can be displayed; each encrypted file is provided with an encryption end and an independent encryption program, so that the encrypted files are very secure and difficult to decrypt; and the usage efficiency of the U disk is fully improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for securely encrypting a USB disk. Background technique [0002] With the popularization of computer applications, U disks are widely used in secret-related systems, which makes U disks an important object for criminals to steal secrets. Especially mobile storage products, because data information needs to be frequently exchanged on multiple computers, or used by multiple people, so the protection of information security is particularly important. Most of the encrypted USB flash drives only emphasize the individual key authentication of the USB flash drive, which can only be used confidentially and cannot be used universally; at the same time, after entering the encryption area, the encrypted USB flash drive on the market can only be unplugged if the user wants to leave temporarily. When the encrypted U disk is used again, the encrypted U disk can only be ...

Most of the encrypted U disks only emphasize the individual key authentication of the U disk, which can only be used confidentially and cannot be used universally; at the same time, after entering the encryption area, if the user wants to leave temporarily, the encrypted U disk on the market can only be unplugged. When the encrypted U disk is used again, the encrypted U disk can only be reinserted into the machine, which is very inconvenient and not safe
