Abstract

A data processing device is targeted at effectively executing the verification of data correctness, preventing from leaking encrypted key information, eliminating incorrect use of storage message data, privilege processing of storage message, storage message applicable to multiple data format and efficiency of regeneration processing of compressed data. By means of the check with the partial check value concerning partial data set of stored message is used to execute partial data authorization processing; by means of partial check value authorization use check of check value to perform authorization processing with respect to all partial data set, making partial check value set of partial check value combination to conduct authorization processing. In addition, the data encryption processing is used to create main key of necessary individual key in memory and generate the key in terms of necessity. Furthermore, concentration management data of storage data is used to accommodate illegal machine list and is used to execute reference list while using and processing data. Then use to accommodate the existing key and system common key of data processing device and follow the stored data usage restriction to selectively use the key. Then, by multiple links to storage data sector, proceeding encryption on at least one partial of storage message by encrypted key Kcon. After encryption, make the encrypted key data of the encrypted Kcon by way of encrypted Kdis to involve in collection portion. Next, make storage data as compressed storage data and delayed process program, or the combination of compressed program classification so as to let regeneration apparatus form a delayed process program applied to compressed storage data.
