Embodiment Construction

[0017] Please see figure 1 , the computer system includes a data processing module 100 , a storage device 200 and a data protection device 300 . Wherein, the storage device 200 may be a hard disk, a U disk, or the like. The data processing module 100 includes a motherboard, a CPU, and a B10S (basic input / output system), and is used for reading / writing data in the storage device 200 through the data protection device 300 . The data protection device 300 is a chip arranged on the motherboard, which has independent instructions and can be used as an independent user operating system for encrypting and decrypting data entering and leaving the storage device 200 . In other implementation manners, the data protection apparatus 300 may also be disposed in the storage device 200 . The data protection device 300 includes a password storage unit 301, an information acquisition unit 309, a key generation unit 311, a key storage unit 313, an input unit 303, a password verification unit ...

Abstract

The invention discloses a data protecting device, which is used for encrypting and decrypting data flowing between storage equipment and a data processing module. The data protecting device is used for encrypting and decrypting the data to be written into the storage equipment and to be read from the storage equipment respectively according to proprietary information in at least one of the data processing module and the data protecting device and a user password. In addition, the invention also provides a data protecting method.

Description

technical field [0001] The invention relates to the field of encryption and decryption, in particular to a data protection device and method for a storage device. Background technique [0002] As we all know, a large amount of user data and application programs of a computer are usually stored in a storage device, such as a hard disk. Usually, access to the hard disk does not require any authorization, but in actual use, in order to ensure that the data in the hard disk is not read / copied at will, the computer system password is generally set to prevent unauthorized personnel from accessing the data stored in the hard disk. [0003] However, because the computer system password only prohibits unauthorized personnel from entering the operating system on the hard disk, so as to avoid random reading / copying of the data in the hard disk. Unauthorized personnel only need to remove the hard disk from the original computer, install the hard disk on another computer, and set the ha...
