Binary mode collision-proof method with safe mechanism in RFID

Abstract

The invention discloses a binary anti-collision method with a security mechanism in RFID, comprising: a new low-cost security authentication mechanism and a conventional RFID binary anti-collision method. The main contribution of the invention is that the conventional electronic tag binary anti-collision method is vulnerable to various attacks such as eavesdropping and tracking, and the invention enhances the security performance of RFID by introducing a new security authentication mechanism. From the perspective of application, the present invention combines physical methods and cryptographic mechanisms, and proposes a new way to solve the RFID privacy problem, which includes a Hash encryption module, a cycle counting address selection circuit, an anti-malicious test self-destruction module, and a terminal database. The present invention adopts Hash encryption technology and a plurality of pseudonym technologies comprehensively, can be applied in distributed RFID application system, and its main technical characteristic is: do not use Hash encryption module in label, but adopt Hash encryption module in RFID reader, like this More than 20,000 circuits can be saved in the label. In addition, the establishment of multiple pseudonyms can effectively prevent being tracked. The invention not only realizes the encryption function, but also can effectively reduce the cost of the electronic label, and is beneficial to the large-scale promotion of the RFID label in the market.

Description

technical field [0001] The invention relates to the field of RFID (Radio Frequency Identification, radio frequency identification), in particular to a binary anti-collision method with a security mechanism applied in low-cost RFID. Background technique [0002] In the 1960s, the first electronic item monitoring and anti-theft system began to be put into commercial operation. Today, RFID has been widely used in various fields, from keyless car opening, animal tracking, highway toll collection to commercial supply chain management, RFID can be seen everywhere. [0003] With the large-scale application of RFID, the problems exposed in security and privacy have attracted more and more attention, mainly in the following aspects: data security threats, personal privacy threats and cloning threats. [0004] One of the threats to data security is that competitors may illegally collect enterprise RFID data, seriously endangering business secrets. The second threat is that RFID itse...

Problems solved by technology

The anti-collision method based on binary tree search is a deterministic method, which has been adopted by ISO / IEC18000-6 and EPC Classl Gen2 standards. Its advantages are strong anti-collision ability, simple data structure and instructions, and its disadvantage is that it supports relatively large storage capacity. Small
