Description

Technical Field

[0001] The present invention belongs to the field of electric communication technology, in particular to the field of radio frequency identification technology, and specifically relates to an encrypted secure communication method and system for short-distance communication radio frequency identification. Background Art

[0002] RFID technology can be used for data communication, but there is a big problem with RFID technology, which is that it is difficult to encrypt during the communication process, which makes it easy to leak information during the data communication process, causing data leakage and further losses. During line inspections, RFID tags are set at different locations on the line to record parameter data at the corresponding locations. During the inspection process, traditional RFID technology is used to read parameter data, which can easily cause data leakage.

[0003] Therefore, based on the above technical problems, it is necessary to design a new encryption and security communication method and system for short-range communication radio frequency identification. Summary of the invention

[0020] Furthermore, a database is provided in the RFID terminal, and / or the RFID terminal is connected to a database, so as to determine the wavelength spacing corresponding to the identification code and the first contact point corresponding to the identification code that needs to be connected through the database.

[0021] Furthermore, the database stores a unique wavelength spacing corresponding to each identification code and a first contact point that needs to be connected and corresponds to the RFID tag corresponding to the identification code.

[0022] Furthermore, after the RFID terminal scans the identification code, the second contact point of the RFID terminal contacts the first contact point of the RFID tag.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 4 As shown, in at least one embodiment, an encrypted secure communication method for short-distance communication radio frequency identification is provided, including: a radio frequency identification terminal, used to build a secure communication protocol; the encrypted secure communication method includes: identifying the key parameter data of the RFID tag, and establishing a secure band communication with the RFID tag after identifying the RFID tag, and updating the parameter data in the RFID tag after establishing the communication; in the key identification code set on each RFID tag, the spacing between two adjacent stripes is adapted to the wavelength spacing corresponding to the RFID tag to complete the short-distance communication radio frequency security identification; wherein the RFID tags are respectively set on the lines, and are configured with key parameter data corresponding to the lines; encryption is implemented during the RFID communication process to ensure data security; RFID communication is encrypted through image recognition to ensure the security of data transmission.

[0042] In the identification code set on each RFID tag, the spacing between two adjacent stripes is adapted to the wavelength spacing corresponding to the RFID tag (that is, a in the figure represents the wavelength spacing corresponding to the RFID tag); each RFID tag corresponds to a waveform with a unique wavelength spacing, and the encryption level in the data communication process is increased by changing the wavelength spacing of the waveform; the wavelength spacing is converted into the distance between adjacent vertical lines or graphics in the identification code, completing the combination of waveform distance encryption and identification code encryption, further increasing the security of data transmission and communication; the wavelength corresponding to the RFID tag itself is different from the wavelength used in traditional RFID communication.

[0043] A plurality of first contacts are arranged on the shell; the first contacts are connected to the coil; the shape of the coil in each RFID tag is different, and first contacts are arranged on the coil, and the number and position of the first contacts are also different, so that the coil is in a disconnected state under normal conditions; and the number of first contacts on the shell can be greater than the number of first contacts required for the coil to be connected, that is, not every first contact is connected to the coil, and the coil needs to be connected through the first contact when parameter data needs to be read or updated.

When the corresponding content in the RFID tag needs to be read or updated, the second contact is brought into contact with the first contact; when the RFID tag needs to be read, the first contact can be brought into contact with the second contact. At this time, the image recognition module can accurately capture the image of the identification code, thereby facilitating accurate identification of the identification code.

[0046] The RFID terminal is provided with a database, and / or the RFID terminal is connected to the database, so as to determine the wavelength spacing corresponding to the identification code and the first contact point that needs to be connected corresponding to the identification code through the database; the database stores the unique wavelength spacing corresponding to each identification code and the first contact point that needs to be connected corresponding to the RFID tag corresponding to the identification code; after the RFID terminal scans the identification code, the second contact point of the RFID terminal contacts the first contact point of the RFID tag, and at this time, the identification code is matched with the information stored in the database to determine that the coil in the RFID tag is connected to the first contact point that needs to be connected, and at this time, the corresponding second contact point contacts and connects with the first contact point, and the scanning terminal sends a frequency band signal corresponding to the wavelength spacing, so that the RFID terminal establishes communication with the RFID tag to identify or update the parameter data recorded in the RFID tag; the information corresponding to all identification codes is stored in the database in advance; multiple encryption is completed through hardware identification and matching to increase the security of the communication process.

[0047] In other embodiments, a communication system using the above-mentioned encrypted secure communication method for short-range communication radio frequency identification is also provided, including: a radio frequency identification terminal and a plurality of RFID tags; the RFID tags are respectively arranged on the line; the radio frequency identification terminal is suitable for scanning the RFID tags.
