Problems solved by technology

[0005] In the patent document CN103345453A, a hard disk data encryption card supporting a SATA interface and an encryption and decryption method are disclosed. The hard disk encryption completed by the encryption card in the document is only completed by writing a software program in the encryption card. Once the encryption algorithm is cracked , unable to prevent the leakage and theft of data information

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with exemplary embodiments with reference to the accompanying drawings.

[0036] like figure 1 Shown is a schematic diagram of an exemplary embodiment of the device encryption module system structure according to the present invention. The encryption module of this device is located between the computer motherboard and the hard disk, and is used as a separate module to connect the two. The computer motherboard is connected to the encryption module through the SATA interface, and the encryption module is connected to the hard disk device through the SATA interface. The SATA interface is Serial ATA. Acronym for Serial ATA. This is a new type of hard disk interface that is completely different from parallel ATA, and it gets its name because it transmits data in a serial manner. The SATA bus uses an embedded clock signal and has stronger error correction capabilities. Compared with the past, its bigges...

Abstract

The invention relates to the field of hard disc encryption, in particular to an SATA hard disc device encryption method and system. The method comprises the following steps that a hard disc device is electrified, whether a secret key storage module exists is detected, if the secret key storage module exists, a device encryption module completes secret key loading, and if the secret key storage module does not exist, the step finishes; the device encryption module judges whether a secret key is correct, if the secret key is correct, the hard disc and a computer complete read and write functions, and if the secret key is incorrect, the computer and the hard disc cannot complete read and write. The system comprises the device encryption module for completing encryption and / or decryption of the data transmission between the hard disc and a main board and the secret key storage module for storing the secret key. By means of the SATA hard disc device encryption method and system, the whole disc encryption of the connected hard disc device is achieved, and sensitive data leakage caused by loss or theft of the hard disc device is avoided.

Description

technical field [0001] The invention relates to the field of hard disk encryption, in particular to a SATA hard disk device encryption method and system. Background technique [0002] As a resource, information is of special significance to human beings due to its universality, sharing, value-added, processability and multi-utility. The essence of information security is to protect information resources from various types of threats, interference and destruction, that is, to ensure the security of information. According to the definition of the International Organization for Standardization, the meaning of information security mainly refers to the integrity, availability, confidentiality and reliability of information. Information security is an issue that any country, government, department, or industry must attach great importance to, and it is a national security strategy that cannot be ignored. [0003] At present, hard disk devices, as the main carrier of data storage...
