In 2007, Chen et al. proposed a RFID authentication protocol for anti-counterfeiting and privacy protection. A feasible security mechanism for anti-counterfeiting and privacy protection was proposed using XOR and random number shifting operations to enhance RFID tags security providing a low cost. However, their authentication protocol has some drawbacks and security problems because they did not consider the surrounding environments. We conduct analysis on the protocol and identify problematic areas for improvement of the research. We also provide an enhanced authentication scheme based on the comment.
