摘要

In order to detect tampering of a protection control module, without informing a detection module of key data for or features of the protection control module, a detection module is provided that detects tampering of the protection control module by validating whether or not there is a correct correspondence between input data to and output data from an application decoding process performed by the protection control module. Also, a plurality of detection modules each validate different slices of the data, thereby preventing the application output data from leaking to the detection modules.
