摘要： The present invention provides a migration apparatus that realizes safe migration of data between devise that use different encryption algorithms and different security authentication levels. The fourth electronic terminal device 2502 sends, to the migration authority 2501, a request for migration of a virtual machine to the fifth electronic terminal device 2503. If the fifth electronic terminal device 2503 is not an illegitimate device, the migration authority 2501 sends a migration request to the fifth electronic terminal device 2503. The fifth electronic terminal device 2503 sends, to the migration authority 2501, a digital signature and so on, together with the request. The migration authority 2501 makes a judgment. If the result is “OK”, the migration authority 2501 sends the result “OK” to the fifth electronic terminal device 2503. The fourth electronic terminal device 2502 encrypts a migration package and sends the encrypted migration package to the migration authority 2501, and sends the virtual machine to the fifth electronic terminal device 2503.

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 having the key database with the tree structure, when deleting or adding a key from/to the tree structure, refers to the encryption strength comparison table and the process time comparison table 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 during the data encryption/decryption process, thus achieving a high-speed data encryption/decryption.

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.
