DATA PROCESSOR, AND DATA PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a data processor which can improve the security of application programs operated on a server device when providing services using an integrated circuit such as ICs. SOLUTION: An external memory 7 stores a plurality of application programs respectively constituted by a plurality of sets of application element data APE and table data for AP control. A SAM chip 8 performs the processing related to services based on the application element data APE. In the processing, key data for performing communication with other SAM chips 8a and an IC card 3 is obtained by referring to the table data for AP control in the processing.
