Abstract
The present invention aims to perform tamper detection on a protection control module without having detection modules come to know the key data and functions thereof. The detection modules of the present invention perform tamper detection by verifying whether or not the correspondence between the input and output data of the application decryption process performed by the protection control module is correct. Furthermore, the present invention offers improved security against leaks of the application output data by the detection modules by having a plurality of detection modules verify different data blocks.
