Abstract
An authentication method of a storage device includes an authentication device requesting an EID (Encoded IDentifer) from the storage device for authenticating the storage device, the authentication device receiving the EID and restoring original ID information by decoding the received EID, and finally the authentication device verifying, by using ID authentication information received from the storage device, individual ID information corresponding to use of the storage device included in ID information, wherein the ID information includes multiple pieces of individual ID information corresponding to the use of the storage device.
Claims17
An authentication method of a storage device, the authentication method comprising:
- requesting, by an authentication device, an EID (Encoded IDentifier) from the storage device by an authentication device, for authenticating the storage device;
- receiving, by the authentication device, the EID from the storage device in accordance with the request;
- restoring original ID information by decoding the received EID;
- and
- verifying individual ID information corresponding to use of the storage device included in ID information by using ID authentication information received from the storage device,
- wherein the ID information includes multiple pieces of individual ID information corresponding to the use of the storage device.
An authentication device for authenticating a storage device, the authentication device comprising:
- an ID decoder for requesting an EID (Encoded IDentifier) to the storage device, receiving the EID from the storage device in accordance with the request, and restoring original ID information by decoding the received EID;
- and
- an authenticator for verifying individual ID information corresponding to use of the storage device included in ID information by using ID authentication information received from the storage device,
- wherein the ID information includes multiple pieces of individual ID information corresponding to the use of the storage device.
A storage device comprising:
- an EID area which is positioned at a particular area of the storage device, and stores an EID for specifically identifying the storage device;
- and
- ID authentication information comprising information for verifying ID information;
- and
- a controller for controlling the EID and the ID authentication information to be transferred to a authentication device, for authenticating the storage device,
- wherein the ID information comprises multiple pieces of individual ID information corresponding to use of the storage device.
