The RFID ultra-high-frequency safe air interface protocol comprises the RFID tag, the reading device, a communication antenna, a background system, a bidirectional authentication mechanism and a storage protection mechanism of the RFID tag, the reading device is used for realizing information interaction with the RFID tag, the communication antenna is arranged between the reading device and the RFID tag, the background system is used for realizing information interaction with the reading device, the bidirectional authentication mechanism is arranged between the reading device and the RFID tag, a safety module is embedded in the reading device, another safety module is embedded in the RFID tag, bidirectional authentication is realized between the reading device and the RFID tag via the safety modules, and safety protection to storage of the RFID tag is realized by the aid of the safety modules and grading of storage areas of the RFID tag. Compared with the prior art, the RFID ultra-high-frequency safe air interface protocol has the advantages that interaction frequency is reduced, interaction time is shortened, and simultaneously safety performance of RFID application is improved.

Description

technical field [0001] The invention relates to an RFID safety communication method, in particular to an RFID ultra-high frequency safety air interface protocol applied to a vehicle-related environment. Background technique [0002] Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology (hereinafter referred to as RFID technology) realized by radio frequency communication. RFID tags have the characteristics of small size, large capacity, long life, and reusability, and can support fast reading and writing, non-visual identification, mobile identification, multi-target identification, positioning and long-term tracking management. Combining RFID technology with Internet, communication and other technologies can realize item tracking and information sharing on a global scale. RFID technology is used in logistics, manufacturing, public information services and other industries, which can greatly improve management and operation ef...

Problems solved by technology

[0004] At present, the research on the UHF dedicated security air interface protocol in the vehicle-related environment is basically in a blank stage at home and abroad. The existing research on the security of the RFID air interface protocol includes: the Hash-Lock protocol [1] uses metaID to hide the ID of the tag, and then Use the background database to find the real ID of the tag; the repeated encryption protocol [2] rewrites the tag content through a third-party organization. The above two data interactions that require a long time when processing RFID tag data are difficult to meet the needs of vehicles involved in rapid movement. Interact with label data under
