Embodiment 1

[0069] see figure 1 , shows the data processing method in the first embodiment of the present invention, applied to electronic tags, including steps S01 to S03.

[0070] Step S01, when a read signal sent by a radio frequency card reader is received, obtain plaintext data corresponding to the read signal.

[0071] Among them, electronic tags, also known as radio frequency tags, are the carrier of RFID (Radio Frequency Identification, radio frequency identification technology). . According to the power supply mode of electronic tags, it can be divided into active tags and passive tags. The energy of active tags comes from its built-in power supply. Tags can carry various sensors, collect information, and form the entrance of the Internet of Things data network collection, but the cost is high and the service life is limited. The energy of the passive tag comes from the radio frequency energy emitted by the tag reader, and it does not need a built-in power supply. It has the a...

Embodiment 2

[0109] Please check Figure 5 , shows the data processing method according to the second embodiment of the present invention, which is applied to an electronic tag, and includes steps S11 to S17.

[0110] Step S11, when receiving the reading signal sent by the radio frequency card reader, acquire plaintext data m corresponding to the reading signal.

[0111] Step S12, obtaining the private key d and the base point coordinate G of the elliptic curve, and randomly generating a random number K, the base point being any point on the elliptic curve.

[0112] Wherein, the base point coordinate G is the coordinate data under the affine coordinate system, and its expression form is G(x, y).

[0113] Step S13 , converting the base point coordinate G in the affine coordinate system to the base point coordinate G in the Jacobi coordinate system according to a preset coordinate transformation formula.

[0114] Wherein, the expression form of the base point coordinate G under the Jacobia...

Embodiment 3

[0164] Please check Figure 6 , shows the data processing method according to the third embodiment of the present invention, applied to a radio frequency card reader, including steps S21 to S22.

[0165] Step S21 , sending a read signal to the electronic tag, and receiving the signature data and plaintext data m fed back by the electronic tag in response to the read signal.

[0166] Among them, the radio frequency card reader is used to identify electronic tags, such as Figure 7 As shown, it mainly includes a control system, and a radio frequency analog front-end composed of a transmitting circuit and a receiving circuit. The control system mainly performs the functions of signal encoding, decoding, encryption and decryption; controls the communication between the application software and the label, and executes the code instructions issued by the system software. The functions of the RF analog front end include: generating high-frequency transmitting power, modulating the ...

Abstract

The invention provides a data processing method, an electronic tag and a radio frequency card reader, and relates to the technical field of radio frequency identification. The data processing method comprises the following steps: when the electronic tag receives a reading signal sent by a radio frequency card reader, obtaining plaintext data corresponding to the reading signal; the electronic tagcalculates signature data of the plaintext data based on an elliptic curve algorithm; the electronic tag transmits the plaintext data and the signature data to the radio frequency card reader together; the radio frequency card reader receives signature data and plaintext data fed back by the electronic tag for the reading signal; and the radio frequency card reader carries out signature verification on the signature data based on an elliptic curve algorithm and judges whether the plaintext data is correct or not according to a verification result. According to the data processing method, an elliptic curve algorithm is adopted to carry out signature processing on the data needing to be sent by the electronic tag, equivalently, a mechanism of mutual authentication between the electronic tagand the radio frequency card reader is added, and therefore the legality and safety of information transmission are ensured.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a data processing method, an electronic tag and a radio frequency card reader. Background technique [0002] UHF RFID (Radio Frequency Identification, radio frequency identification) technology has the ability to read multiple electronic tags at one time, strong penetrability, multiple read and write, large data memory capacity, low cost and small size of passive electronic tags , easy to use, high reliability and long life, has been valued by countries all over the world. [0003] A radio frequency card reader, also known as a tag reader, is an automatic identification device that uses UHF RFID technology to read electronic tag data. When in use, the radio frequency card reader sends a reading instruction to the electronic tag to read the data on the electronic tag. [0004] However, in the prior art, the current communication between the electronic tag ...
