Abstract: Disclosed is a storage device, which includes a nonvolatile memory device, and a controller that controls the nonvolatile memory device. In response to a first command, a barrier command, and a second command being received from an external host device, the controller supports an order guarantee between the first command and the second command. Each of the first command and the second command is selected from two or more different commands. In response to a request from the external host device, the controller circuitry is configured to provide the external host device with a device descriptor associated with the ordering.

Abstract: Provided are an operating method of a storage device and an operating method of a storage system including the storage device. An operating method of a storage device including a nonvolatile memory device and a storage controller includes storing, by the storage controller, a public key received from a first host, transmitting, by the storage controller, a random number to a second host in response to a host authentication start request from the second host that has obtained the public key and a private key corresponding to the public key, receiving, by the storage controller, a signature generated based on the private key and the random number from the second host, verifying, by the storage controller, the signature based on the public key, and changing, by the storage controller, a first device parameter according to a request from the second host in response to the signature being verified.
