PROBLEM TO BE SOLVED: To provide a new method and a device for imparting security countermeasures, enabling a secure collaborative relationship among processors in a multi-processor system. SOLUTION: The method and the device are provided, in the multi-processor system including the plurality of processors operatively connected to a main memory 106, and correlated respectively with a local memory; and at least one main processor 102E capable of controlling access to data in the main memory 106 and data in the processors. In the method and the device, at least one processor 102A enters a secure operation mode, and access of another processor other than at least one processor 102 to data correlated with at least another processor 102C different from other processors other than at least one processor 102A among the plurality of processors is forbidden by using the main processor 102E.
