Real-time Traffic monitoring systems need to monitor the vehicles as well as it requires to communicate with the vehicle to provide the real time information about traffic density, road construction, etc. However, insecure communication between these entities can lead to life-threatening scenarios. Therefore, there is a dire need to develop appropriate protocols facilitating communication between vehicles to vehicles and vehicles to the traffic monitoring systems. In this paper, we propose a new AEAD-based protocol embedded with physically Unclonable Function (PUF) based key generation for secure and authenticated transmission of videos for real-time monitoring systems. The proposed protocol consists of a lightweight AEAD primitive - ACORN; and a hardware-efficient LFSR-based Ring Oscillator PUF (RO-PUF). The proposed PUF based key generation adds another layer of security to our protocol. Our protocol is implemented in FPGA using a 640 × 480 resolution camera with 30 frames per second. Detailed implementation study of the entire protocol shows its feasibility for real-world usage.
