Security Analysis for UHF RFID Tags

With RFID applications being used more widely, their security risks are growing. Especially, there are many threats in the security of tags in RFID system. Due to their physical structure, plenty of vulnerabilities exist in memory bank and simple communication protocols. In this paper, we analyze the vulnerabilities of memory banks, detail the treats of the vulnerabilities in the cases of different numbers of tags and different distances between tags and readers. Finally we design attack cases to verify the vulnerabilities in reading and writing operation of tags.
