Abstract
Conference Title: 2015 IEEE Vehicular Networking Conference (VNC) Conference Start Date: 2015, Dec. 16 Conference End Date: 2015, Dec. 18 Conference Location: Kyoto, Japan Existing RFID schemes targeting traffic management contexts are mainly conceptual and prototypical. Little attention has been given to the important issue of authentication. With the rapid migration to cloud-based technology, there is a pressing urgency for addressing authentication in toll/ traffic RFID solutions. This paper presents a toll/ traffic RFID authentication scheme which benefits from the well-known Merkle Hash Trees. The main benefit of MHTs is its scalability compared to traditional schemes. In order to increase scalability, we propose a scheme that significantly lowers the computation complexity of the traditional MHTs. In our proposed scheme, we achieve better performance and improve traditional MHTs by a simple division mechanism. Initial evaluation results demonstrate these benefits and show promising direction for further research.
