摘要
PROBLEM TO BE SOLVED: To provide an efficient data processing apparatus.;SOLUTION: This data processing apparatus includes: a data processor processing data in a secure mode having access to secure data that is not accessible to the data processor in a non-secure mode; and a further processing device performing a task including processing of data including the secure data in response to a request from the data processor. The further processing device starts processing of the secure data using a secure key and storage of the processed secure data into a non-secure data store in response to a task temporary stop signal, and starts taking-out of the processed secure data from the non-secure data store and restoration of the processed secure data using the secure key in response to a task resumption signal. The secure key is securely stored such that it is not accessible to other processes operating in the non-secure mode.;COPYRIGHT: (C)2009,JPO&INPIT
