    Abstract: A structure that can perform an efficient process to update a revocation list in a memory card is realized. This structure includes a data processing unit that controls updating of the revocation list to be stored into a data storage unit, and the data processing unit acquires a revocation list URL from a server that performs data recording on the data storage unit, and acquires the revocation list from a revocation list providing server by using the acquired revocation list URL. The acquired revocation list is further recorded into the data storage unit. In the recording process, a data writing process command that does not include the revocation list is input from a server, the acquired revocation list is inserted into the command, a process based on the command is performed, and the revocation list is recorded.
