Nowadays Internet of Thing (IoT) technology has accessed all the aspects of our life. One of the IoT applications is the smart transportation. Smart transportation gains a lot of attention, as it is part of the smart cities. The data transmission in smart transportation is done through the wireless communication and especially through the Vehicular ad hoc networks (VANETs) which made the data vulnerable to many issues concerning security. Therefore, security techniques should be applied to secure vehicle’s user data. In this paper, the RC5 encryption algorithm will be used as a security technique to protect users’ privacy in smart transportation. The simulation of RC5 will be implemented with FPGA using Quartus Prime Lite Edition version 18. The purpose is to check hardware resources of RC5 and make sure it is suitable for smart transportation. © 2019 IEEE.
