Information storage device, information processing system, information processing method, and program

An information processing system, comprising:

• an information storage device that has a storage unit and a controller;
• a license management apparatus, comprising:
• a first central processing unit (CPU);
• and
• a first memory coupled to the first CPU, wherein the first memory comprises first instructions for causing the first CPU to generate a media key set (MKS) which is an inherent key set stored in the information storage device;
• a controller manufacturing apparatus, comprising:
• a second central processing unit (CPU);
• and
• a second memory coupled to the second CPU, wherein the second memory comprises second instructions for causing the second CPU to manufacture the controller stored in the information storage device;
• and
• a media manufacturing apparatus comprising:
• a third central processing unit (CPU);
• and
• a third memory coupled to the third CPU, wherein the third memory comprises third instructions for causing the third CPU to manufacture the information storage device,
• wherein the license management apparatus is configured to:
• set an MKS version that depends on a date and a time of the generation of the MKS, to be in the MKS;
• and
• provide the MKS to the media manufacturing apparatus,
• wherein the controller manufacturing apparatus is configured to:
• store an allowance minimum MKS version, that depends on a date and a time of the manufacture of the controller, in the controller;
• and
• provide the controller to the media manufacturing apparatus, and
• wherein the media manufacturing apparatus is configured to:
• insert the controller into the media;
• input the MKS into the controller;
• compare the MKS version recorded in the MKS and the allowance minimum MKS version;
• and
• based on the MKS version that is equal to or greater in value than the allowance minimum MKS version, record in the storage unit, a media public key and a media private key that are included in the MKS.

An information processing method, comprising:

• in an information storage device:
• receiving, by an interface of the information storage device, a media key set (MKS) from a license management apparatus,
• wherein the MKS is inherent to the information storage device;
• determining, by a controller of the information storage device, a MKS version and key information based on the received MKS;
• recording, by the controller of the information storage device, the key information in a storage unit of the information storage device based on the MKS version that is equal to or greater in value than an allowance minimum key version,
• wherein the allowance minimum key version is recorded in advance in the controller;
• generating, by the controller of the information storage device, a media key binding log based on the key information;
• and
• outputting, by the controller of the information storage device, the generated media key binding log to the license management apparatus.

A non-transitory computer-readable storage medium having stored thereon, computer-executable instructions for causing a controller of an information storage device to execute operations, the operations comprising:

• controlling an interface of the information storage device to receive a media key set (MKS) from a license management apparatus,
• wherein the MKS is inherent to the information storage device;
• determining a MKS version and key information based on the received MKS
• recording the key information in a storage unit of the information storage device based on the MKS version that is equal to or greater in value than an allowance minimum key version,
• wherein the allowance minimum key version is recorded in advance in the controller;
• generating a media key binding log based on the key information;
• and
• outputting the generated media key binding log to the license management apparatus.

An information storage device, comprising:

• wherein the MKS is inherent to the information storage device;
• a storage unit;
• and
• a controller configured to:
• determine a MKS version, a media public key, and a media private key based on the received MKS,
• wherein the media public key and the media private key are inherent to the information storage device;
• record the media public key and the media private key in the storage unit based on the MKS version that is equal to or greater in value than an allowance minimum key version,
• wherein the allowance minimum key version is recorded in advance in the controller and is based on a date of manufacture of the controller;
• generate a media key binding log based on the media public key and the media private key;
• and
• output the generated media key binding log to the license management apparatus.
