AB  - Due to the development of the Internet of Vehicles (IoV) and advanced 
      driver-assistance 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 FlexRay/Ethernet 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 one-to-one mapping logic, the execution 
      times of FlexRay to the Ethernet path and Ethernet to FlexRay path are constant, 
      at 4.67 mus and 6.71 mus, respectively. In particular, cybersecurity can be 
      integrated as an extension of the gateway with low latency and power consumption.
