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.

Abstract: A storage system includes a host device supporting multiple queues and a storage device communicating with the host device. The host device may include first and second cores, first and second queues corresponding to the first and second cores and storing commands, and a host controller that sets a queue ID and/or a parallelism demand level for each commands stored in the first and second queues. The storage device may include nonvolatile memories and a storage controller that detects pattern information of commands, received from the host device, based on the queue ID and places the commands, received from the host device, in the nonvolatile memories based on the pattern information.
