Radio frequency identification authentication system and method based on quantum cryptography network

Abstract

The invention belongs to the field of encryption communication of a quantum cryptography network, and provides a radio frequency identification authentication system and method based on the quantum cryptography network. The radio frequency identification authentication system based on the quantum cryptography network comprises a server, a reader, a quantum key card and a label, the ID of the reader and the corresponding authentication key thereof, and the ID of the tag and the corresponding authentication key thereof are stored in a database of the server; the server and the reader are respectively and correspondingly connected with the quantum key card, so that the server and the reader are subjected to identity bidirectional authentication through a quantum encryption channel; the reader and the tag communicate with each other through a radio frequency field, the server and the tag also adopt a bidirectional authentication mode to authenticate the identity, and when the bidirectional authentication of the identity between the reader and the server and the identity between the server and the tag succeeds, the radio frequency identification authentication succeeds.

Description

technical field [0001] The present disclosure belongs to the field of encrypted communication of quantum cryptographic networks, and in particular relates to a radio frequency identification authentication system and method based on quantum cryptographic networks. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The Internet of Things is a physical Internet that covers everything in the world based on the computer Internet, using radio frequency identification (Radio Frequency Identification, RFID), sensing and other technologies to construct a physical Internet that covers everything in the world. next wave. With the wide application of the Internet of Things in various fields of social life, its security problems are particularly prominent, and the security authentication of readers and tags in the RFID system has become the most import...

AI Technical Summary

Problems solved by technology

[0006] The current radio frequency identification authentication method has the following problems: 1) In the classic server-based authentication protocol, due to the limitation of the computing power and storage space of the tag, the tag can only realize the authentication process through the hash or MAC operation of a single key; The authentication code calculation

Because the radio frequency identification system works in an open network environment, anyone may monitor the content of the communication, so the reused key used to calculate the authentication code is easy to be cracked, jeopardizing the security of the authentication protocol, thus threatening the entire Security of RFID communications

2) In the communication process between the reader and the server, the authentication key cannot be updated in time, which makes the authentication process between the reader and the server a potential safety hazard
