Abstract

The invention discloses an encrypted storage system and method, and belongs to the technical field of solid state disks. When a storage terminal is started, the storage terminal generates a key pair that comprises a public key and a private key corresponding to the public key, and the key pair is lost if being powered down; the storage terminal sends the public key to a key storage terminal via anencryption terminal; the key storage terminal adopts the public key to encrypt the encrypted key to form a ciphertext, and sends the ciphertext to the encryption terminal; the encryption terminal sends the ciphertext to the storage terminal; and the storage terminal decrypts the ciphertext to acquire the encrypted key according to the stored private key, and encrypts a data file written into thestorage terminal by using the encrypted key. The abovementioned technical scheme has the beneficial effects that the key storage can be separated from the hard disk, the security of the data file is enhanced, and the key management becomes more convenient and flexible.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, in particular to an encrypted storage system and method. Background technique [0002] The hard disk is the most important storage medium in the computer. The traditional hard disk is realized by the mechanical hard disk. The advantage of the mechanical hard disk is that the price is relatively low, the storage capacity is large, and the applicability is relatively wide. However, the read and write efficiency of the mechanical hard disk is low, and the data security The guarantee is also relatively poor, and the storage controller-related technologies of mechanical hard disks are monopolized by foreign giants, which has resulted in the failure of domestic mechanical hard disk technology to advance, and there will be no hardware encryption hard disks that meet the encryption algorithm specifications of the State Cryptography Administration of China. [0003] Solid state drive is a n...
