Binary mode collision-proof method with safe mechanism in RFID

Abstract

The invention discloses a binary system anti-collision method with a security mechanism in RFID, which comprises a new low-cost security authentication mechanism and a routine RFID binary system anti-collision method. The major contribution of the invention lies in that: a routine electronic tag binary system anti-collision method is easy to suffer wire tapping, tracing and various attacks; through introducing the new security authentication mechanism, the invention strengthens the safety performance of the RFID. From the point of view of application, the invention combines a physical method with a cipher mechanism and proposes a new approach to solve the problem of RFID privacy; the security authentication mechanism comprises an Hash encryption module, a cycle count addressing circuit, an anti-malicious test self-destruction module, a terminal database, etc. The invention comprehensively adopts Hash encryption technology and a plurality of pseudonym technology and can be applied to a distributed RFID application system; the invention has the main technical characteristics: the Hash encryption module is not used in the tag, but the Hash encryption module is adopted in an RFID reader; therefore, 20 thousand of multi-door circuits can be saved in the tag; in addition, the binary system anti-collision method with a security mechanism in RFID can prevent from tracing through the setting of a plurality of pseudonyms . The method not only realizes the encryption function, but also effectively reduces the cost of the electronic tags and is favorable for large-scale popularization of the RFID tags 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 Class1 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
