Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1, in combination with the embodiment of the present application, an anti-counterfeit verification method of an NFC electronic tag is provided, including:
s101: the NFC tag supplies power to target equipment of near field communication and initiates a wireless signal started by the NFC tag;
s102: after receiving the wireless signal started by the NFC tag, the target device starts a verification terminal to generate a challenge signal by the verification terminal and sends the challenge signal to the NFC tag;
s103: the Physical Unclonable Function (PUF) circuit in the NFC tag receives the challenge signal, the physical unclonable function of the PUF circuit generates a corresponding response value according to the challenge signal, and the NFC tag sends the response value corresponding to the challenge signal to the verification terminal;
s104: the verification terminal compares the response value with a registration response value corresponding to the NFC tag identification identity; when the response value generated by the PUF circuit is equal to the registration response value, the NFC tag is proved to pass verification, otherwise, the NFC tag is not proved to pass verification; wherein, the registration response value refers to: and in the verification end, a unique response value obtained by responding the challenge signal by a physical unclonable function corresponding to the user identity of the NFC tag.
Since the physical unclonable function (PUF, physically unclonable function) refers to a random physical factor that is unpredictable and uncontrollable during the device manufacturing process, resulting in a micro-physical structure that has small differences, a challenge-response relationship is created between different device units on the input and output signals that is independent of each other, and since it is not possible to clone devices with the same challenge-response, this relationship is called a physical unclonable function. Each PUF chip has the following characteristics: (1) uniqueness: each chip is randomly distributed and unique; (2) anticounterfeiting properties: the chip itself is extracted from the uncertainty in the chip manufacturing process, and the same PUF value cannot be duplicated again; (3) unpredictability: there is no way to predict the chip before it is manufactured; (4) tamper-evident: the PUF value of the chip cannot be positioned and modified, extraction is convenient, extraction is performed in a circuit structure every time the chip is started, and the chip has uniqueness and cannot be tampered.
Therefore, for the NFC electronic tag with the unique identity registered at the target equipment verification end, the physical unclonable function is unique, when a challenge signal is initiated to the PUF circuit, the response signal is also unique, and the challenge-response relationship of the PUF circuit is a physical one-way function relationship, so that the physical one-way function relationship is difficult to mathematically model and predict, and is difficult to crack. Therefore, when the non-encrypted NFC tag is started through the target equipment after the UID is copied after being read and written easily, and when the challenge signal is received, the corresponding response signal is different from the registration response value of the NFC tag with the real identity, so that the cloned NFC tag can be judged to be a card class which is not identified, such as a fake card, and the real NFC tag is ensured not to be stolen. Similarly, after the secret key of the encrypted NFC tag is revealed or the detected channel is attacked, the NFC tag is copied and cloned, but when the NFC tag is started by the target device, a challenge signal is received, the response signal is different from the registration response value of the NFC electronic tag of the real identity, and then the cloned NFC tag is judged to be a card type which is not identified such as a fake card, so that the identity uniqueness of the NFC tag can be ensured, the safety of the NFC tag is ensured, and the safety of the application environment of the target device is ensured.
Preferably, the anti-counterfeiting verification method of the NFC electronic tag further comprises the following steps:
s105: after the target device starts the verification terminal, the verification terminal acquires a user identity from the NFC tag and verifies the user identity of the NFC tag;
s106: if the user identity of the NFC tag fails to pass the verification of the verification end, indicating that the NFC tag fails to pass the verification, and ending the verification; the verification terminal does not initiate a challenge signal to the NFC tag;
s107: and if the user identity of the NFC tag passes the verification of the verification terminal, further generating a challenge signal by the verification terminal.
When the user identity of the NFC tag fails to pass the verification at the verification end of the target device, the NFC tag is indicated to be not a true NFC tag matched with the target device and is not allowed to be used. After the user identity of the NFC tag passes the verification at the verification end of the target device, whether the NFC tag is a real tag or not needs to be further verified through a physical unclonable function, if so, the NFC tag is allowed to be used, otherwise, the NFC tag is forbidden, and the safety of the NFC tag and the safety of the environment where the target device is applied can be ensured. The NFC tag is protected by the identification number code (unique user identification) of the NFC tag, and a layer of firm protection measures are added.
Preferably, the anti-counterfeiting verification method of the NFC electronic tag further comprises the following steps:
s108: extracting unique physical unclonable functions of each NFC label from the chip of each NFC label aiming at each NFC label for the target equipment, and storing the unique physical unclonable functions in the verification terminal, namely a label registration process; the physical unclonable function refers to a physical structure with small differences formed by uncertain factors in the manufacturing process of the chip, wherein the physical structure enables the chip to have registration response values which are unique and different from other chips respectively when facing the same challenge signal. Since the physical unclonable function (PUF, physically unclonable function) refers to a random physical factor that is unpredictable and uncontrollable during the device manufacturing process, resulting in a micro-physical structure that has small differences, a challenge-response relationship is created between different device units on the input and output signals that is independent of each other, and since it is not possible to clone devices with the same challenge-response, this relationship is called a physical unclonable function. Each PUF chip has the following characteristics: (1) uniqueness: each chip is randomly distributed and unique; (2) anticounterfeiting properties: the chip itself is extracted from the uncertainty in the chip manufacturing process, and the same PUF value cannot be duplicated again; (3) unpredictability: there is no way to predict the chip before it is manufactured; (4) tamper-evident: the PUF value of the chip cannot be positioned and modified, extraction is convenient, extraction can be performed in a circuit structure after each chip is started, and the chip has uniqueness and cannot be tampered.
Before the NFC tag is applied, a tag registration is required, and the challenge and response relationship of the unique physical unclonable function in the chip of the NFC tag are extracted for verifying whether the NFC tag is a real NFC tag or not when the NFC tag is used, not a counterfeit NFC tag. Therefore, in the application, the NFC label can increase the physical anti-counterfeiting capacity on the basis of mathematical anti-counterfeiting safety, and greatly improves the anti-counterfeiting, tamper-proofing and copy-proofing capacity of the NFC label.
Preferably, the anti-counterfeiting verification method of the NFC electronic tag further comprises the following steps:
s109: and the NFC antenna arranged on the NFC tag receives the challenge signal and transmits the challenge signal to the Physical Unclonable Function (PUF) circuit in the NFC tag through a bus interface.
