  • Publication number: 20230289089
    Abstract: Disclosed herein is a data storage device. A data port transmits data between a host computer system and the data storage device. A non-volatile storage medium stores encrypted user content data and a cryptography engine connected between the data port and the storage medium uses a cryptographic key to decrypt the encrypted user content data. The access controller generates authorization request data indicative of multiple devices to be authorized, and stores the authorization request data on non-volatile configuration memory of the data storage device. Upon approval of the authorization request data by a manager device that is registered with the access controller as a manager device, the access controller locates the authorization request data of one of the multiple devices to be authorized and registers the one of the multiple devices to be authorized as an authorized device.

  • Patent number: 11741214
    Abstract: Data storage devices, methods, and systems for passcode authentication based on automatically generated and dynamically changing unlock passcodes are described. An access controller of a data storage device is configured to receive a first passcode based on an externally generated input passcode that is synchronized with internal generation of an unlock passcode by the access controller. The access controller generates a second passcode based on the internally generated unlock passcode, and unlocking the data storage device is responsive to the first passcode matching the second passcode.

  • Patent number: 11606206
    Abstract: Disclosed herein is a data storage device comprising a data path and an access controller. The access controller generates a recovery private key, generates encrypted authorization data based on the recovery private key, stores the encrypted authorization data, and sends the recovery private key to a manager device. When recovery is desired, access controller receives a recovery public key, calculated based on the recovery private key, from a recovery manager device, decrypts the encrypted authorization data based on the recovery public key, generates a challenge for the recovery manager device based on the decrypted authorization data, sends the challenge to the recovery manager device over the communication channel that is different from the data path, receives a response to the challenge from the recovery manager device over the communication channel, and based at least partly on the response, enables decryption of the encrypted user content data.

  • Publication number: 20220417249
    Abstract: A data storage device including a biometric reader for biometric authentication to enable access to a storage medium. The data storage device is configured for remote registration of a remote user of the data storage device, wherein registration includes receiving a record of a biometric authentication data set of the remote user from a secure database. Alternatively, a secure authorizing command is received remotely from an authorization server to enable the data storage device to directly read and store biometric data of the remote user. The data storage device can be unlocked by biometric authentication to enable a host device to access user data in the storage medium.

  • Patent number: 11469885
    Abstract: Disclosed herein is a data storage device with storage medium that stores encrypted user content data. A cryptography engine uses a cryptographic key to decrypt the encrypted user content data. An access controller receives, from a user device, a request to register the user device and generates a challenge for a manager device. The manager device is located remotely from the data storage device. The controller sends, to the user device, the challenge for the manager device; receives, from the user device, a response calculated by the manager device to approve the request to register; calculates the cryptographic key based at least partly on the response calculated by the manager device; and creates and stores authorization data associated with the user device. The authorisation data indicates the cryptographic key, to register the user device with the data storage device.

  • Patent number: 11366933
    Abstract: Disclosed herein is a data storage device comprising a data path and an access controller. The data path comprises a data port configured to transmit data between a host computer and the data storage device and registers with the host computer system as a block data storage device. A non-volatile storage medium stores encrypted user content data. A cryptography engine is connected between the data port and the storage medium and uses a key to decrypt the encrypted user content data. A data store stores multiple entries comprising authorization data associated with respective authorized devices. The access controller receives from a manager device a public key associated with a private key stored on a device to be authorized, creates the authorization data, and stores the authorization data in association with the public key in the data store, thereby registering the device to be authorized as one of the authorized devices.

  • Publication number: 20220121781
    Abstract: This disclosure relates to data storage device (DSD) hardware and, more specifically, to systems and methods for encrypting data stored on a DSD. A DSD comprises a non-volatile storage medium to store multiple file system data objects using block addressing. A device controller is integrated with the DSD and comprises hardware circuitry configured to encrypt data to be stored on the storage medium. The controller receives a request for an encrypted file system data object from a host computer system, identifies one of the ranges of blocks where the requested encrypted file system data object is stored on the storage medium, and sends the file system data object stored in the identified range of blocks to the host computer system in encrypted form as stored on the storage medium.
