Title:
INFORMATION PROCESSING DEVICE, ADMINISTRATION DEVICE, INVALID-MODULE DETECTION SYSTEM, INVALID-MODULE DETECTION METHOD, RECORDING MEDIUM HAVING AN INVALID-MODULE DETECTION PROGRAM RECORDED THEREON, ADMINISTRATION METHOD, RECORDING MEDIUM HAVING AN ADMINISTRATION PROGRAM RECORDED THEREON, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2011/033773
Kind Code:
A1
Abstract:
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.
