Safe radio frequency identification system

Abstract

The invention discloses a safe radio frequency identification system comprising an antenna A (4), an antenna B (7), a radio frequency channel module (8), a control processing module (9), an integrity memory unit (10), a verification unit B (12), an identity authentication unit (17) and an integrity verification unit (18), wherein the antenna A (4) is respectively connected with a chip (5) and a verification unit A (6) in a bidirectional mode; the antenna A (4) is connected with the antenna B (7) in a wireless radio frequency mode; the safe radio frequency identification system finishes the safe bidirectional identity authentication among a background application system (3), a reader (2) and a label (1) and establishes radio frequency identification network connection mutually trusted; and the background application system (3) finishes the integrity verification of the information of the label (1) and the reader (2) after establishing the connection. The invention provides two levels of safe protection, and the information is transmitted in a cipher text mode so as to guarantee the reality, the integrity and the confidentiality of the transmission information.

Description

technical field [0001] The invention relates to a radio frequency identification system, in particular to a safe radio frequency identification system. Background technique [0002] Radio Frequency Identification (Radio Frequency Identification, referred to as "RFID") system is a non-contact automatic identification system that uses radio frequency signals to automatically identify target objects to obtain relevant data and process the data. [0003] The radio frequency identification system includes three parts: tags, readers and background application systems. The tag includes: antenna and chip, each chip contains a unique identification code, and maintains agreed electronic data; the reader includes: radio frequency channel module, control processing module and antenna, which are read according to needs and using corresponding protocols It communicates with the device that writes the information of the label, so as to complete the acquisition, decoding, identification an...

AI Technical Summary

Problems solved by technology

However, these authentication protocols have the following deficiencies: they do not have the function of mutual authentication among tags, readers and background application systems; they cannot resist effective attacks or can only resist partial attacks; Conducive to application production

At present, there is no safe, efficient, and practical low-cost radio frequency identification security authentication protocol, and these security solutions only provide a single level of security protection measures, lacking the security of private information in tags and readers. However, it cannot guarantee the authenticity, confidentiality and integrity of private information in the process of transmission at the same time.
