Abstract: A nonvolatile memory system includes a nonvolatile memory device having a physical storage area, and a memory controller managing the physical storage area on the basis of first and second logical areas. The memory controller is configured to receive a logical block address range corresponding to a part of the first logical area and a command from a host and is configured to receive data, a logical block address and a write command from the host to perform an update with respect to the second logical area. When, in the update operation, the received logical block address is included in the logical block address range, the memory controller, in response to the write command, redirects the received logical block address to a logical page number of the second logical area so that the data is written in the second logical area.

Abstract: A storage device includes a memory device storing data, and a controller controlling the memory device. The controller obtains and stores a certificate including a public key of an administrator from a host device, provides a nonce to the host device in response to a request from the host device, receives a token request signature including the nonce, a user identifier (ID), an allowed command list and a lifetime from the host device, and when it is verified that the token request signature is generated by a legitimate administrator by decrypting the token request signature with the public key, generates a token for allowing a user corresponding to the user ID to execute a command included in the allowed command list during the lifetime, and a token secret key corresponding to the token, and provides the token and the token secret key to the host device.

Abstract: In one embodiment, the method includes receiving, at a storage device, a request. The request includes a request message authentication code and write protect information. The write protect information includes at least one of start address information and length information. The start address information indicates a logical block address at which a memory area in a non-volatile memory of the storage device starts, and the length information indicates a length of the memory area. The method also includes generating, at the storage device, a message authentication code based on (1) at least one of the start address information and the length information, and (2) a key stored at the storage device; authenticating, at the storage device, the request based on the generated message authentication code and the request message authentication code; and processing, at the storage device, the request based on a result of the authenticating.
