The invention discloses a label generation circuit with a physical non-replicable function. The label generation circuit comprises a constant current source module, a capacitive sensor, a signal acquisition module and a microprocessor which are integrated on the same chip and are connected in sequence. The constant current source module is used for charging the capacitive sensor with a constant current until the capacitive sensor is fully charged after the chip is electrified. The signal acquisition module is used for acquiring charging response information of the capacitive sensor in the charging process and outputting the charging response information to the microprocessor. The microprocessor is used for generating a physical non-replicable function label according to the charging response information. Different chips generate different charging response information due to processing errors. According to the invention, the chip can generate a unique and non-reproducible physical non-reproducible function label, so that the security problem of the Internet of Things chip is solved, and a new technical scheme thought is provided for solving the security problem of the chip.
Description
technical field [0001] The invention relates to the technical field of electronic chips, in particular to a generating circuit and method for a physical non-replicable functional label. Background technique [0002] The application fields of the Internet of Things involve all aspects, and the application in the infrastructure fields such as industry, agriculture, environment, transportation, logistics, security, etc., effectively promotes the intelligent development of these aspects, making the limited resources more reasonable.
