Design of a FlexRayEthernet Gateway and Security Mechanism for InVehicle Networks Due to the development of the Internet of Vehicles (IoV) and advanced driverassistance systems (ADAS), the Ethernet has become one of the most important communication protocols for the future of automotive networks. This is because the existing communication protocols (such as FlexRay) do not provide sufficiently high bandwidth requirements. The main challenge for the automotive industry will be to transfer and extend standard IP and Ethernet into vehicles and still fulfill the automotive requirements. The automotive gateway not only links two or more protocols and exchanges the data using each, but also monitors and ensures functional safety. This paper proposes a FlexRayEthernet gateway by considering the development conditions of embedded systems and the security in the field of vehicle networking. The proposed method is implemented on the Field Programmable Gate Array (FPGA) system to evaluate running time and to analyze the overhead of the security mechanism. For onetoone mapping logic, the execution times of FlexRay to the Ethernet path and Ethernet to FlexRay path are constant, at 4.67 xcexbcs and 6.71 xcexbcs, respectively. In particular, cybersecurity can be integrated as an extension of the gateway with low latency and power consumption.

Secure message propagation protocols for IoVs communication components Abstract   With the development of Internet of Vehicles (IoVs), the smart transportation field has achieved a lot of attention by providing a wide variety of benefits, such as enhanced road safety, reduced traffic congestion, traveler safety, and less pollution. It made the concept of xe2x80x98intelligence on wheelsxe2x80x99 into a real one. However, the highly dynamic nature of vehicles and insecure channels are the significant challenges in an IoV environment. In the existing researches, secure and lightweight protocols for the IoVs communication components are missing. In this paper, we design secure and lightweight communication protocols for different components of IoVs, such as V2V (VehicletoVehicle), V2P (VehicletoPortable Device), V2R (VehicletoRoad Side Unit), V2I (VehicletoInfrastructure), and V2S (VehicletoSensor). We have done indepth security analysis to ensure the resistant power against different strong attacks. Moreover, we have implemented the protocols on a Desktop Computer and Raspberry Pi. From the results, it is observed that the proposed protocols perform well in the perspectives of communication, storage, computation, and battery consumption than other competitive protocols.
