Abstract |
|
|
| A mobile RFID system is a radio frequency identification technology that allows users to read the information on its tags.
When this free reading function is combined with a mobile RFID system featuring radio frequency identification, it may violate an
individuals privacy. This is because others may obtain personal information by reading the tags. In addition, user tracking can be a
problem, because the fixed ID values of tags can be traced in network segments. Although various solutions have previously been
proposed to resolve this RFID privacy problem, most of these solutions involve numerous calculations within the tags. Therefore, these
techniques can only be applied to expensive active tags with high-capacity embedded processors. In addition, it is not practical to
apply these techniques to a mobile RFID system based on passive tags attached to devices because of the increase in the price and
volume of the tags themselves. In this paper, we propose an efficient protocol that can be used to implement authentication functions in
order to transfer the high-performance calculation functions to mobile devices, thus storing only the resulting values on the tags. This
study mainly focuses on improving the limitations of the existing RFID authentication functions, which usually assume active tags. It
shows that the same security level and performance can be obtained through passive tags. The proposed protocol meets various security
requirements such as tag protection, location- and traffic-tracking prevention; the proposed protocol also meets other requirements such
as lightweightness and the desired level of performance. |
