Abstract: An electronic device includes at least one processor, a first storage unit configured to store a secret value set by a host, a second storage unit configured to store a boot loader code, a first firmware code, and a second firmware code, and a read-only memory (ROM) configured to store a ROM code executable in a booting operation. The ROM code, when executed, may cause the at least one processor to generate a first booting value based on the secret value and a first hash value for the boot loader code, the boot loader code, when executed, may cause the at least one processor to generate a second booting value based on the first booting value and a second hash value for the first firmware code, and the first firmware code, when executed, may cause the at least one processor to generate a third booting value based on the second booting value and a third hash value for the second firmware code.

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.

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 controller includes a key generator, an encryption and decryption circuit, and a processor. The key generator generates a first security key and a second security key based on a write request from a host. The encryption and decryption circuit encrypts write data corresponding to the write request based on the first security key to generate encrypted write data, and encrypts the first security key based on the second security key to generate a first encrypted security key. The processor controls nonvolatile memories such that the encrypted write data, the first encrypted security key, and the second security key are programmed in at least one of the nonvolatile memories, and controls the nonvolatile memories such that a dummy program operation is performed on a page of the nonvolatile memories in which the second security key is programmed instead of erasing the encrypted write data.
