TERMINAL IDENTIFICATION PROCESSING SYSTEM

摘要

PURPOSE:To speed up and simplify a processing by using unidirectional conversion of a rapid processing without using cipher processing requiring decoding. CONSTITUTION:Unidirectional conversion to be executed more rapidly and simply than cipher processing to be decoded is used and its converted result is matched by an identifying device. Namely, an identification processing part 12 is constituted of a random number generator(RAN) 121, an exclusive OR computing element(XOR) 122 and a unidirectional conversion part(ONE-WAY) 123. The identification processing part 22 is provided with a comparator(COMP) 224 in addition to the constitutional element of itself. Consequently, the processing can be speeded up and simplified.
