摘要:
In one embodiment, the method includes obtaining, at the external device, an encrypted main key and an encrypted first decryption key from the memory device. The encrypted first decryption key is an encrypted version of a first decryption key. The encrypted main key is an encrypted version of the main key. The external device is unable to read the main key from the memory device. The method further includes decrypting, at the external device, the encrypted first decryption key using a second decryption key to obtain the first decryption key; and decrypting, at the external device, the encrypted main key of the memory device using the first decryption key to obtain the main key.

In one embodiment, the memory device includes a first memory area and a second memory area. The first memory area stores secure data. The first memory area is inaccessible by an external device. The second memory area is configured to store encrypted secure data. The second memory area is accessible by the external device, and the encrypted secure data is an encrypted version of the secure data in the first memory area.
摘要:
A storage system that enables the use of a plurality of keys respectively stored in a plurality of storage units of a storage device is provided. The storage system includes a storage device including a first storage unit and a second storage unit that are recognized as a single storage device, wherein the first storage unit is configured to store a first key, the second storage unit is configured to store a second key different from the first key, and a controller is configured to transmit to the storage device one of a first key-read control signal that includes information about the first storage unit and a second key-read control signal that includes information about the second storage unit and receive the first key and the second key as identification information of the storage device in response to the first key-read control signal and the second key-read control signal, respectively.
