The innovative Open image in new window protocol of Juels and Weis  extends device authentication to low-cost RFID tags. However, despite the very simple on-tag computation there remain some practical problems with Open image in new window and despite an elegant proof of security against some limited active attacks, there is a simple man-in-the-middle attack due to Gilbert et al. . In this paper we consider improvements to Open image in new window in terms of both security and practicality. We introduce a new protocol that we denote random-Open image in new window. This proposal avoids many practical drawbacks of Open image in new window, remains provably resistant to attacks in the model of Juels and Weis, and at the same time is provably resistant to a broader class of active attacks that includes the attack of . We then describe an enhanced variant called Open image in new window which offers practical advantages over Open image in new window.
