The Research On Tag Status Detection And Security Mechanisms Based On The WISP

With the continuous expansion of RFID (Radio Frequency Identification, RFID)technology application fields, people put forward higher requirements for the diversityof the Tags data and privacy protection. Traditional passive tags only simpleidentification of goods, so the function is relatively simple, and can not use the tags toreal-time detection of the state of the target. In this paper, we combined theWISP(Wireless Identification and Sensing Platform) to carry out the research work forthe application of the passive sensor tag and RFID privacy protection. RFID integratedtest platform has been designed and implemented,it was meet the needs of people fordata diversity of tag. Improved EPC C1G2(EPC Class-1Generation-2) standardprotocol, to a certain extentis protect user privacy.This thesis uses WISP’s characteristics, we focus our research work on thefollowing aspects:(1)The author will further study of the composition and working principle of theWISP,including WISP hardware components, computing and storage capacity, powerconsumption, communication standards, data modulation Etc. Focus on research andanalysis of the EPC C1G2UHF RFID air interface protocol. Combined with the WISPdeveloped Gen2tag,and implemented tag EPC number obtain,as well as dataacquisition of sensors.(2)On this basis, in order to realize state detecting of the tags, the paper design anddevelop RFID integrated test platform, the platform achieved tags classificationstatistics, read rate detection for the tag, the sensor data dynamic display Etc. Byfunctional testing of the platform, it can not only test whether the various functionalmodules to meet demand, but also test the function of Gen2tag. Through the test,completing validation of the function that identity and sensing of tags,Tags andproving the practical value of the WISP.(3)In order to make better use of the open source nature of the WISP, We research onsome lightweight RFID security authentication protocol and EPCC1G2standardprotocol. Then we found a lot of security risks for Gen2protocol.This thesis contrary to prohibit unauthorized access, anti-tracking, anti-spoofing security needs, we haveimproved standard protocol. In order to protect user privacy, this thesis increasedactivation and sleep state in Gen2tags.Finally, this thesis gived hardware feasibility andsafety analysis.Based on the WISP, the author gives a further test through simulation.In this thesis, the author designed and developed WISP tag,and RFID integratedtest platform, achieved real-time detection of tag status. Improvement andimplementation of UHF EPC C1G2protocol using the platform, protected users’privacy a certain extent, and enhanced the security performance of the RFID system.
