Security analysis of the santi-magda elliptic curve-based RFID protocol

In this paper, we describe a man-in-the-middle attack against one of the high confidence and efficient privacy RFID protocols recently proposed by Santi and Megda. The attack, during which an intruder can impersonate a valid reader or a tag and forge a set of messages to communicate with the honest agents, destroys the assumed authentication of the protocol, one of the important properties of secure protocol.
