  • Storage device sharing data encryption key as encrypted and operating method of storage device
    Patent number: 11381388
    Abstract: A storage device includes a nonvolatile memory device, and a controller that manages a data encryption key (DEK). The DEK is used to encrypt data to be written in a storage space of the nonvolatile memory device by a first user and to decrypt data read from the storage space. The controller grants a second user authority to access the storage space by encrypting the DEK based on a Diffie-Hellman (DH) algorithm, grants a second user authority to access the encrypted DEK, and decrypts the encrypted DEK based on the DH algorithm.

  • Cradle assembly attachable to a vehicle
    Patent number: 8985630
    Abstract: A cradle assembly for a vehicle having an underbody is provided. The cradle assembly includes a cradle body attachable to the underbody of the vehicle by at least one fastener. The cradle body may define at least one pathway, which may have a first pathway portion and a second pathway portion between which the at least one fastener is movable. The at least one fastener may be positioned in the first pathway portion to enable the cradle body to be secured to the underbody, and in the second pathway portion to enable the cradle body to be separated from the underbody. The cradle body is configured to move with respect to the at least one fastener when an applied load on the vehicle is at or above a threshold magnitude.
