High-security radio frequency identification method, device and system based on bidirectional authentication

Abstract

The invention relates to the technical field of radio frequency identification, and discloses a high-security radio frequency identification method, device and system based on bidirectional authentication. The method comprises the following steps of: carrying out pre-authentication by using an index code and a shared key according to an authentication request in the form of a timestamp, carrying out ID confirmation by using a random number and a multi-key public key algorithm, and carrying out bidirectional final authentication by using the random number, the key and the ID. The device comprises a server, a radio frequency reader-writer and an electronic tag; the system comprises a processor, a storage device and a high-security radio frequency identification device based on bidirectional authentication. Bidirectional authentication of the tag and the reader-writer is realized, the device has good security and privacy protection characteristics, and the security and risk resistance of communication are ensured.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a high-security radio frequency identification method based on two-way authentication. Background technique [0002] Radio Frequency Identification (RFID) is an important technology of the Internet of Things. It is a wireless communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets. The advantage is non-contact identification, which can penetrate snow, fog, ice, paint, dirt and harsh environments where barcodes cannot be used to read labels (commonly known as cards such as bank cards, bus cards, etc.), and the reading speed is extremely fast, and in most cases it is not to 100 milliseconds. Radio signals transmit data from a tag attached to an item through an electromagnetic field tuned...

AI Technical Summary

Problems solved by technology

Third parties can monitor, interfere, and tamper with the conversation between tags and readers, and the integrity and availability of information is difficult to guarantee

The security of the communication channel between the tag and the reader is a problem to be solved in the field of RFID research.

The existing RFID authentication protocols are all one-way authentication protocols, which can only solve the problem of the reader's authentication of the label's legitimacy, but cannot solve the problem of the tag's verification of the reader. Dynamic authorization of readers affects the promotion of large-scale RFID network applications
