Problems solved by technology

[0005] Existing authentication protocols often adopt a one-way authentication process, that is, the verification machine checks the authenticity of the RFID electronic tag, and the RFID electronic tag cannot check the authenticity of the verification machine
One-way authentication is suitable for completely passive occasions, but not suitable for occasions that require two-way authentication

Embodiment Construction

[0123] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0124] figure 1 For the identification relationship between the electronic tag and the Reader, between the writer (Writer), the electronic tag, and the card reader (Reader), the electronic tag in the figure represents an RFID electronic tag, and a password is set in the electronic tag Simple dynamic devices such as generators and random number generators barely interact with card readers for authentication. This mutual authentication cannot be equal, because the card reader is an active smart device, while the electronic tag is a passive memory device. This creates an insurmountable fatal loophole. Recently, the cracking of the smart card Mifare and the emergence of ...

Abstract

The invention discloses an RFID (radio frequency identification) system and an RFID method based on bidirectional authentication. The system comprises an RFID electronic label with a data unit and a control unit. The data unit comprises 5 independent data areas, each of which comprises a plurality of data items. The control unit comprises 5 independent control parameters mi, an interstage module 2 offset register FSRi, and a combined gate circuit. A proof machine and the RFID electronic label are utilized to perform bidirectional authentication. Without a CPU (central processing unit), the RFID electronic label has authentication and control functions. As a storage tool, the RFID electronic label can provide authenticity evidences for the RFID electronic label, and also can detect the authenticity of the proof machine, so that the copy attack and the code attack are both prevented. The system can be applied to payment systems like an E-wallet, and high-grade anti-fake and anti-copy one-card multipurpose systems such as bills and certificates.

Description

technical field [0001] The invention relates to an RFID identification and authentication system and method, in particular to an RFID system and method through two-way identification. Background technique [0002] At present, radio frequency tag RFID (RFID, Radio Frequency IDentitity) technology has been used in various fields such as bus cards, electronic wallets, manufacturing, material circulation, clothing, payment systems, bills and certificates, etc., reflecting the needs of various businesses in a concentrated manner. Its security problem is more serious than that of wired Ethernet, and it faces security problems. Before secure communication, the security identification and authentication problem between the reader and the electronic tag in the RFID system must be effectively resolved. In recent years, in addition to the radio frequency card (RFID), a wireless smart card (smart card) Mifare has been developed. In addition to the storage function, the smart card also ...
