EIGEN-DEVICE INFORMATION GENERATION APPARATUS, EIGEN-DEVICE INFORMATION GENERATION SYSTEM AND EIGEN-DEVICE INFORMATION GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an eigen-device information generation apparatus for generating eigen-device information at high speed by means of a simple circuit or method, an eigen-device information generation system and an eigen-device information generation method.;SOLUTION: The eigen-device information generation apparatus includes: a physically unclonable function circuit (PUF) 3 for generating an intrinsic signal R1 depending on physical properties of a device in response to an input signal C; a converter 102 which generates a converted signal by converting the intrinsic signal R1 and stores the converted signal in a database DB; and a decoder 103 for decoding a signal generated in accordance with an intrinsic signal R2 that is generated in response to the input signal C which is inputted again, and the converted signal stored in the database DB.;COPYRIGHT: (C)2015,JPO&INPIT
