Abstract
A storage device includes: a controller; a storage medium coupled to the controller; and a data security bridge comprising a security module and a key management module; wherein the security module is configured to perform data encryption and/or data decryption; and wherein the key management module is configured to obtain a first security key stored in the storage device, obtain a second security key received by the storage device, and perform a user authentication based on the first security key and the second security key.
Claims38
A storage device comprising:
- a controller;
- a storage medium coupled to the controller;
- and
- a data security bridge comprising a security module and a key management module;
- wherein the security module is configured to perform data encryption and/or data decryption;
- and
- wherein the key management module is configured to obtain a first security key stored in the storage device, obtain a second security key received by the storage device, and perform a user authentication based on the first security key and the second security key.
A method performed by a storage device, the method comprising:
- obtaining a first security key from a medium in the storage device;
- obtaining a second security key stored in an external device;
- performing a user authentication by a key management module in the storage device based on the first security key and the second security key;
- and
- retrieving encrypted data from a storage medium in the storage device based at least in part on a result of the act of performing the user authentication.
