Abstract

The Radio Frequency Identification (RFID) is an important technology of the Internet of Things. Along with the rapid growth of the RFID technology, security issues have acquired much attention recently. However, most of the RFID security works focus on fake identity or information leaking problems. Researchers seldom care about the security of system mechanism, such as media access control. This paper focuses on the anti-collision mechanism of ISO15693. We analyze the 16-slot anti-collision in ISO15693 in detail, demonstrate access vulnerability, present a potential attack approach of similar-tags collision and validate the attack efficiency through simulation. Afterwards, an improved anti-collision paradigm is proposed to mitigate the similar-tags attack. The empirical study shows that the improved anti-collision tactic is much more efficient than that in ISO15693.
