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.

Abstract: A memory card includes a nonvolatile memory and a device controller. The nonvolatile memory stores data. The device controller divides the nonvolatile memory into a plurality of logical units and stores an authentication program at a partial area the plurality of logical units. When connected with a host, the device controller enables the authentication program to be executable on the host.

Abstract: A method of writing data in a replay protected memory block (RPMB) area of a storage device in response to a request of a host device includes receiving a write request, including a message authentication code, data, and a bitmap index, from the host device and verifying the write request based on the message authentication code and the bitmap index. The verifying the write request may include calculating a message authentication code based on data and a bitmap index received from the host device, comparing a message authentication code, calculated in the storage device, with the message authentication code of the write request, and comparing the bitmap index of the write request with bitmap indexes, stored in the storage device, to check whether a replay attack has been made.

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.
