Abstract

This application discloses a key management method and system, and relates to the field of information security. The main technical solution of this application is: receiving the input user key, performing hash operation on the user key to obtain the hash value of the user key; reading the encrypted value of the data key from the storage medium, using the user key The key hash value decrypts the encrypted value of the data key to obtain the data key, and uses the data key to encrypt or decrypt user data. By adopting the key management method and system provided by this application, the software running on the storage device cannot directly access the key for encrypting and decrypting data, thereby achieving hardware-level protection of the key and reducing the risk of leakage.

Description

technical field [0001] The present application relates to the field of information security, in particular to a key management method and system for data encryption or decryption of storage devices. Background technique [0002] figure 1 A block diagram showing the memory device. The storage device 102 is coupled with the host, and is used to provide storage capabilities for the host. The host and the solid-state storage device 102 can be coupled in various ways, including but not limited to SATA (Serial Advanced Technology Attachment, serial advanced technology attachment), SCSI (SmallComputer System Interface, small computer system interface), SAS (Serial Attached SCSI, serial connection SCSI), IDE (Integrated Drive Electronics, integrated drive electronics), USB (Universal SerialBus, universal serial bus), PCIE (Peripheral Component Interconnect Express, PCIe, high-speed peripheral component interconnection), NVMe (NVM Express, high-speed non-volatile storage), Etherne...
