碩士 === 國立交通大學 === 資訊管理研究所 === 93 === There are many applications with Radio Frequency Identification (RFID), and it is the solution to replace the barcode. Because of the features of RFID, many people emphasis the issues about security and privacy. After Wal-Mart proceed “Smart-Sheft” testing, Consumers Against Supermarket Privacy Invasion and Numbering (CASPIAN) worried that merchants or manufacturers were able to trace the product which had sold. Although the manufacturers of RFID chips announced that they would embed “Kill”or “Sleep”function in chips, there were other problems. Thus, how to make RFID Tag reuse and ensure privacy is the focus of this dissertation. After reviewing the issues about RFID Tag reuse and privacy, the main point is that RFID Tag keepers worry about leaking information. If no reuse of RFID Tag, that will make RFID lose edges. Thus, this dissertation purposes two mechanisms of RFID Tag reuse that make Tag be reused and provide privacy protection. Mechanism 1 requires shorter computing time and less cost of tags. Mechanism 2 provides higher security when attackers knew the secret key, but it would spend more computing time. There are different advantages for two mechanisms, and which points to the conclusion that we may use one of two mechanisms according to the factors which we consider.
