The Research Of Security And Privacy On The System Of Radio Frequency Identification

Radio Frequency Identification (Identification) technology is one of the ten most influential technologies in this century. RFID technology has been widely used in real life practice. The speciality of the tag resource and the openness of the system, make RFID tags be confronted with important security and privacy problems, for example,to effectively provide the privacy proction for the secret information stored at the tags,and to trace the tag holders.The dissertation firstly introduces the RFID system composition, application,etc. Then we analyze the RFID system security and privacy issues in detail, and the RFID system authentication of existing protocols, analyzes its shortcomings. To fully understand the RFID system in the face of threats and the existing protection scheme based on Hash function, We use a new RFID authentication protocol to protect the safety and privacy information holders, Compared with other schemes, the new scheme is introduced into the timestamp strategy, back-end database mediator entities certification success ID labels last, can prevent the denial of service attacks. Through the analysis, this paper proves good agreement safety, good protecting consumers' privacy.For the active tag, due to its resource is more than the Low-cost tag, We use the more safety performance of elliptic curve cryptography algorithms to construct a new authentication protocol, this agreement can be good protect the system communication .
