Security protocol authentication method based on mobile RFID system

Abstract

The invention discloses a security protocol authentication method based on a mobile RFID system, and relates to the technical field of communications, for realizing security authentication by use of a method of a dynamic ID and a Hash function mechanism. In the authentication process of a protocol, a background server needs to carry out dual verification of an label identification ID and a mobile reader-writer identification RID and updates a label identification after verification succeeds, and an RFID label and a mobile reader-writer are each provided with a pseudorandom number generator and have capabilities of executing Hash operation and XOR logic operation. In each authentication process, a label, the mobile reader-writer and the background server perform transmission and exchange of encryption information, and through such processes of inquiry, response, search, calculation, verification, updating and the like, the effect of security authentication is realized. According to the invention, a new system can fend off various attacks by use of the dynamic ID and the Hash function mechanism.

Description

【Technical field】 [0001] The invention relates to the technical field of communication, and more specifically relates to the problem of security authentication among labels, mobile readers and background servers in a mobile RFID system. 【Background technique】 [0002] Radio frequency identification technology (RFID) is a comprehensive technology that combines non-contact automatic identification technology and data information acquisition technology. It uses radio frequency signals through spatial coupling (alternating magnetic field or electromagnetic field ) realizes non-contact information transmission and achieves the purpose of identification through the transmitted information, and has the advantages of non-contact, simple operation, fast reading and writing, and high reliability. Therefore, RFID technology has been widely used, and its application fields include vehicle transportation and distribution, production automation, logistics identification, mail tracking, ro...

Problems solved by technology

Among them, the physical method has the disadvantages of short service life, low efficiency, and non-reusability. Based on the Hash function encryption mechanism, it is widely used because of the one-way and encryption of the Hash function.

However, existing security protocols cannot fully meet the security requirements of mobile RFID systems.

[0004] This invention is based on the original patent application: RFID security method based on dynamic ID and key update of automobile security system (patent application number: 201410754424.7), aiming at the communication between electronic tags, readers and background servers in the RFID system In the original system, the security and privacy of information transmission between the mobile reader and the background server were not considered, which made the system vulnerable to illegal attacks
