摘要： In the key management software having a key database with a tree structure, a high-speed data encryption/decryption process is achieved by changing the tree structure without reducing the security strength when deleting or adding a key from/to the tree structure. The key management software 135 having the key database 146 with the tree structure, when deleting or adding a key from/to the tree structure, refers to the encryption strength comparison table 170 and the process time comparison table 180 to change the tree structure without reducing the security strength. This reduces the number of times an encrypted key is loaded onto the encryption/decryption processing device 134 during the data encryption/decryption process, thus achieving a high-speed data encryption/decryption.

摘要： A method is provided for flexibly setting a shared counter shared by a plurality of security modules sharing a counter in tree structures, while curbing the amount of secure memory used. The shared counter is realized by a first counter group having a tree structure managed by a first secure module and a second counter group having a tree structure managed by a second secure module sharing a node in the tree structure of the first counter group and a node in the tree structure of the second counter group. The method of sharing using tree structures enables flexibly addition, deletion and access restriction setting of modules that use the shared counter.

摘要： A data storage apparatus is provided that realizes a measure against deterioration of a flash memory in which integrity check data is stored. A content playback apparatus (1000) uses a hash value of playback history information as integrity check data (confirmation data) for confirming whether the playback history information has been falsified. A first address calculation unit (1004) and a second address calculation unit (1006) determine a read-in address and a storage destination address for the integrity check data, with use of the hash value. Accordingly, the storage destination addresses can be diffused, thus enabling preventing deterioration of the flash memory.
