Non-volatile memory for anti-cloning and authentication method for the same

A method for authenticating a non-volatile memory for anti-cloning comprising:

• receiving a request for an Enhanced Media Identification (EMID) from a host device by the non-volatile memory that stores an identification for identifying the non-volatile memory in an EMID area located in a specific area of the non-volatile memory;
• modifying the identification by a preset operation with an arbitrary value;
• and
• transmitting the modified identification to the host device in response to the request,
• wherein the EMID area includes a first area in which reading by an external device is prevented, and a second area in which reading from the non-volatile memory by the external device is permitted in response to a read command.

A non-volatile memory for anti-cloning, comprising:

• an Enhanced Media Identification (EMID) area, which is located in a specific area of the non-volatile memory, and stores an identification for identifying the non-volatile memory;
• and
• an EMID encoder for modifying the identification by a preset operation in conjunction with an arbitrary value,
• wherein the EMID encoder includes an EMID converter for performing an EMID conversion operation, and a black box for generating a random error used for performing the EMID conversion operation.

• modifying the identification by a preset operation with an arbitrary value;
• and
• transmitting the modified identification to the host device in response to the request,
• wherein modifying the identification includes modifying the identification by the preset operation using a random error generated in the non-volatile memory, unique information included in the identification, and a value for EMID encoding, which is received from an authentication device.
