Role-Based Enhancement of Secure Authentication for RF-UCard Systems

Radio Frequency Universal Smart Cards (RF-UCard) open up the possibility for various attacks violating user privacy. In this paper, we propose a strong and lightweight role-based mutual authentication protocol. By employing the mutual authentication and the reader-role validation, the protocol can effectively defend against both passive and active attacks, including the invalid data access from the unauthorized readers. Through the protocol implementation, we observe that the proposed protocol is feasible and practical in RF-UCard systems.
