AI Technical Summary

Problems solved by technology

Moreover, the data encryption method of the existing solid-state hard disk is not full-disk encryption, so it is easy to cause data loss, and its confidentiality performance is weak
In addition, when multiple types of data in the solid-state drive are encrypted with a password, and the password is easily lost, all types of data will be stolen
[0004] In summary, the existing solid-state hard disk data encryption and decryption technology obviously has inconvenience and defects in actual use, so it is necessary to improve it

Abstract

The invention provides a solid-state-drive data encryption and decryption method and a solid state drive, which are applicable to the technical field of storage. The solid-state-drive data encryption and decryption method includes the following steps of dividing at least one physical page address of the solid stage drive into at least one logical independent page address; encrypting data with different sources by different secret keys; and storing the encrypted data with different sources into the at least one physical page address. Therefore, safety of storage data of the solid state drive is improved.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method for encrypting and decrypting data in a solid-state hard disk and the solid-state hard disk. Background technique [0002] Solid State Disk (Solid State Disk) is composed of a control unit and a storage unit (FLASH chip). Simply put, it is a hard disk made of an array of solid-state electronic memory chips. At present, the maximum capacity is more than 1T. The interface specifications and definitions, functions and usage methods of solid-state hard drives are exactly the same as those of ordinary hard drives, and the product shape and size are also completely consistent with ordinary hard drives. Widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields. [0003] At present, SSD users have higher and higher requirements for data security. The...
