Internet of Vehicles (IoVs) is coming and will grow in next few years, VANETs (Vehicular Ad Hoc Networks) is evolving into the era of IoVs. Inevitably, VANETs need to communicate with WSNs (Wireless Sensor Networks). Real-time data transmission between vehicles and road-side sensor nodes has many application scenarios. However, due to different characteristics of VANETs and WSNs, real-time traffic data transmission is too complicated and slow when emergencies occurred in many RSUs-sparse (Road Side Units) areas. In this paper, we propose a broadcast authentication protocol, namely Paralleling Broadcast Authentication Protocol (PBAP), aiming at enhancing energy efficiency and providing network security in the direct communication between vehicles and WSNs. The simulation results demonstrate that the protocol can effectively extend lifetime of WSNs by improving the utilization rate of the keys and show nice properties in different channel loss ratio and different degrees of DoS attacks. The protocol can work well even in the area without RSUs.
