Abstract
A method for authentication, by a host device, of a storage device having a plurality of unit storage areas comprises acquiring information on the distribution of locations of defect referenceive areas to be used for uniquely identifying the storage device, sampling the unit storage areas of the storage device, identifying the distribution of locations of physically defective areas among the sampled areas, determining the similarity between the acquired distribution of locations and the identified distribution of location, and authenticating the storage device according to the result of the determination.
Claims19
A method for a host device to authenticate a storage device having a plurality of unit storage areas, the method comprising:
- receiving, from the storage device, authentication information including a table representing a positional distribution of defect reference areas used for uniquely identifying the storage device;
- sampling the unit storage areas of the storage device;
- identifying a positional distribution of areas having physical defects from among the sampled areas;
- determining similarity between the received positional distribution and the identified positional distribution;
- and
- authenticating the storage device based on a result of the determination.
A non-transitory machine-readable storage medium having recorded thereon a program for executing a method for a host device to authenticate a storage device having a plurality of unit storage areas, the method comprising:
- receiving, from the storage device, authentication information including a table representing a positional distribution of defect reference areas used for uniquely identifying the storage device;
- sampling the unit storage areas of the storage device;
- identifying a positional distribution of areas having physical defects from among the sampled areas;
- determining similarity between the received positional distribution and the identified positional distribution;
- and
- authenticating the storage device based on a result of the determination.
