Research On RFID Security Authentication Protocol

Radio Frequency Identification(RFID) is an automatic identificationtechnology which uses radio frequency that enables wireless data transmissionand can identify objects attached with tags at distance without any contacts.Because RFID system has lots of advantages,make it widely applied. However,the security of the privacy in RFID system itself is drawing more and moreattention with application promotion.Aim at attack model on RFID,after detailed analysis of several kinds oftypical authentication protocol,the thesis put forward two kinds ofauthentication protocol meeting different applications.One is Hash-based KeyConsult Mutual Authentication Protocol(HKCMAP) with high security and lowprice.Another is Key Array based Mutual Authentication Protocol(KAMAP) withvery-high security and relatively high price.HKCMAP can resist replay attack,tag tracking,juggle attack,denial ofservice,inner tag attack and has forward security and backward security.HKCMAP is a key-update protocol.Meanwhile it has low price.KAMAP can resistreplay attack,tag tracking,juggle attack,denial of service,inner attack andhas forward security and backward security.Compare with most of protocol,KAMAP can resist inner attack.So KAMAP is a protocol with very high security,but require higher price.Finally,this thesis realizes the HKCMAP and KAMAP in software in visualstdio2005environment.Through the design of various attacks,it proves thatthis two kinds of protocol can solve the common attacks in RFID system,thusproves their availability.
