Abstract:
Provided are method and system for identifying a legal chip. The method includes a reading device sequentially sending, to a chip to be read, M instructions to be processed comprising N preset instructions (S101); the chip to be read sequentially receiving the M instructions to be processed, and responding to each instruction to be processed (S102); the reading device acquiring a set of first processing durations (S103) the reading device acquiring a processing duration characteristic of the chip to be read (S104); and the reading device acquiring a result of comparing the processing duration characteristic of the chip to be read with a processing duration characteristic of a legal chip corresponding to an identifier of the chip to be read, and determining the chip to be read as a legal chip (S105).
