Problems solved by technology

[0004] With the above three AES key storage methods, any third party can easily access the important data stored in the data storage device as long as the data storage device or software encryption device is taken away from the host computer. There are loopholes; moreover, the data in the data storage device will not be available if the specific data block or the specific chip that stores the key is damaged or the software encryption device that stores the key is lost.

Abstract

The invention provides a data protection system. The system comprises a cloud management platform and at least one data storage device, the cloud management platform comprises a database; the databasestores at least one key, the data storage device comprises a data storage unit, a microprocessor and a network communication assembly. The microprocessor is connected with a cloud management platformthrough a network communication assembly network. The data storage unit comprises a controller and a plurality of flash memories. The flash memory stores a plurality of encrypted data. The microprocessor sends a key extraction request containing a unique code to the cloud management platform, the cloud management platform selects a matched key from the database according to the unique code in thekey extraction request and transmits the selected key to the data storage device, and a controller of the data storage device decrypts encrypted data through the key.

Description

technical field [0001] The present invention relates to a data protection system and method, in particular to a system and method for implementing data protection for a data storage device by using a cloud to provide a key. Background technique [0002] With the demand for data storage, data storage devices, such as solid state drives (SSD), memory cards or flash drives, are often used to store important data. In order to prevent the important data stored in the data storage device from being arbitrarily stolen or copied, a data encryption mechanism is usually added to the data storage device, for example: using a 128-bit or 256-bit key (such as an AES key) to encrypt data storage data stored in the device or decrypted data read from the data storage device. [0003] In the past, the AES key can be stored in a specific data block of the flash memory of the data storage device or in a specific chip (such as EEPROM) of the data storage device. In the process of encrypting an...
