STORAGE MEDIUM AND METHOD AND DEVICE FOR UPDATING REVOCATION INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a storage medium or the like for excluding any access to contents in respect to illegal electronic equipment generated afterwards. SOLUTION: A storage media (PM) 13 is provided with a controller 130 and two kinds of storage areas (a secret area 134 and a public area 131). The public area 131 is provided with a public R/W area 133 for storing digital contents and a public ROM-W area 132a for storing the identification information of electronic equipment being the object of the inhibition of any access to the digital contents as revocation information, and a public ROM area 132 for storing the identification information of the electronic equipment being the object of the inhibition of the update of the revocation information as master revocation information. When this storage medium is mounted on the electronic equipment having the identification information registered in the public ROM area 132, the controller 130 rejects the update of the revocation information by the electronic equipment.
