碩士 === 明新科技大學 === 資訊管理研究所 === 100 === Due to its automatic identification capability and convenience, Radio Frequency Identification (RFID) system is taking the place of barcode and has been applied to various areas such as supply chain, transportation, retail and medical treatment in recent years. However, information transmitted through the air is vulnerable to eavesdropping, interception, or modification due to its radio transmission nature. The data of tags can be read or modified without authorization. The access control of tags is needed to avoid the above attacks. Most existing RFID security protocols only focus on the mutual authentication between the tag and the reader, while the protection of the data transmitted from the tag after the mutual authentication is not included. In this thesis, we analyzed the tag access control of methods used in practice, EPC Class 1 Generation 2 standard and existing protocols in literature. Moreover, an improved protocol is proposed to avoid the above attacks. That allows consumers to enjoy the technological convenience brought by RFID.
