摘要： At least one set of revocation information for identifying electronic appliances that should be revoked for content protection and master revocation information for identifying electronic appliances that have special permission to update the revocation information are recorded in advance into a special storage region on a storage medium. When the storage medium is loaded into an electronic appliance indicated by the master revocation information, the revocation information can be updated. However, when the storage medium is loaded into an electronic appliance indicated by the revocation information, the electronic appliance is revoked and so the protection of contents is improved.

摘要： A storage medium (PM) 13 includes a controller 130 and two types of storage regions, the concealed region 134 and the open region 131. The open region 131 includes an open RW 133 storing a digital content, an open ROM-W region 132a storing, as revocation information, identification information of an electronic appliance that is prohibited from accessing the digital content, and an open ROM region 132 storing, as master revocation information, identification information of an electronic appliance that is prohibited from updating the revocation information. When the storage medium is loaded into an electronic appliance that has identification information which is registered in the open ROM region 132, the controller 130 prohibits the electronic appliance from updating the revocation information.

摘要： A semiconductor memory card comprising a control IC 302, a flash memory 303, and a ROM 304. The ROM 304 holds information such as a medium ID 341 unique to the semiconductor memory card. The flash memory 303 includes an authentication memory 332 and a non-authentication memory 331. The authentication memory 332 can be accessed only by external devices which have been affirmatively authenticated. The non-authentication memory 331 can be accessed by external devices whether the external devices have been affirmatively authenticated or not. The control IC 302 includes control units 325 and 326, an authentication unit 321 and the like. The control units 325 and 326 control accesses to the authentication memory 332 and the non-authentication memory 331, respectively. The authentication unit 321 executes a mutual authentication with an external device.
