Design and Analysis of an FPGA-Based Authentication and Key Establishment Protocol for Mobile-Edge-Assisted RFID–IoT Systems

Mobile Edge Computing (MEC) plays a key role in enabling low-latency RFID–IoT applications by offering localized computation and storage resources. While this improves responsiveness and scalability, it also increases exposure to security and privacy threats. This paper presents an enhanced authentication and key establishment scheme designed to mitigate privacy and security attacks in mobile-edge-assisted RFID-IoT environments. The scheme incorporates password update and recovery mechanisms to enhance practical usability and resilience. Its correctness is verified using BAN logic, and an AMD Xilinx FPGA prototype demonstrates its practical performance. Comparative results show that the proposed scheme offers strong security with low computational and communication overhead, making it suitable for latency-critical edge applications.
