Towards a complete chaotic map-based mobile RFID authentication protocol with efficient anticollision tag indexing.

Radio frequency identification technology is one of the modern popular emerging technologies proven to advance a wide range of applications in both academia and industry. However, potential security risks, privacy issues, and efficiency are still open challenges that must be addressed seriously to achieve enhanced protection. In this paper, we show that the Akgun et al. protocol remains unsafe and imperfect in terms of the security issue and database identification efficiency. We, first, demonstrate that the Akgun et al. protocol suffers from a stolen/lost reader attack, which could expose users to some life threatening situations and unwanted collection of sensitive private information. Second, we found that all indexing identification-based protocols and exceptionally the Akgun et al. protocol cannot be used properly when the collision of tag index occurs, which exhibits a low efficiency in the database entry identification process. As the Akgun et al. protocol is almost perfect, it is worthy to be enhanced. Therefore, towards a complete and secure mobile radio frequency identification authentication protocol, we propose efficient solutions that could overcome the aforementioned security problem and offer high identification efficiency using efficient anticollision procedure based on dynamic linked list data structure principle. Via informal and formal security analysis, we show that the improved version is insensitive to the most common attacks and is more efficient than the existing schemes in the literature.
