Abstract

The invention provides a solid state disk data encryption method and system. The method comprises the steps of obtaining a PIN code; according to PIN, generating a medium key; configuring the medium key in an encryption engine key register; and performing encryption or decryption on user data according to the medium key, wherein the PIN code includes a user PIN code and a default PIN code used for unlocking an encrypted region and a public region respectively, and the medium key is configured to perform encryption or decryption on the data. According to the solid state disk data encryption method provided by the invention, the occupation of calculation resources of a host in the encryption process is reduced through hardware encryption; quick switching among multiple partitions is supported; and the problems of low efficiency and no support of quick switching among the partitions in a conventional encryption method are solved.

Description

technical field [0001] The present application relates to the technical field of solid-state hard disk data encryption, in particular to a solid-state hard disk data encryption method and system. Background technique [0002] A solid-state drive is a hard drive made of an array of solid-state electronic memory chips. The solid-state hard disk includes a control unit and a storage unit, wherein the control unit uses the interface of the storage unit to write data into the storage medium or read data from the storage medium, and provides a data input and output interface for the host. The storage medium of the solid-state hard disk is a non-volatile memory that can still store data after power failure, that is, NAND flash memory. As an important carrier of data and information exchange, solid-state drives must ensure data security during data storage and information exchange. [0003] In order to ensure the security in the process of data storage and information exchange, th...
