FALSIFICATION DETECTION DEVICE AND FALSIFICATION DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a falsification detection device and a falsification detection method allowing a reduction in the time required for starting a program.;SOLUTION: A provided falsification detection device comprises: hash value storage means 507 for storing block program identification information and a comparison hash value that is obtained by applying a predetermined hash function to a block program, in association with each other; selection means 502 for selecting, when a target program is started by a compound machine 100, specific block program identification information 702 stored in the hash value storage means 507 in parallel with the start of the target program; hash value calculation means 508 for calculating a corresponding hash value by applying the hash function to a block program corresponding to the selected specific block program identification information 702; and detection means 510 for comparing the corresponding hash value and the comparison hash value and detecting falsification of the target program when both of them do not match.;COPYRIGHT: (C)2012,JPO&INPIT
