Abstract: The amount of data exchanged in connected vehicles has significantly increased with the increase in number of sensors in the car. Many advanced technologies, such as cloud computing, V2X (vehicle to everything) communication, ADAS (Advanced driver assistance systems), and artificial intelligence, are being more and more widely used in cars, which makes connected cars more intelligent to offer comfortable services for people and ensure the safety of drivers and passengers. However, cyber-attack risk is growing as our vehicles become more interconnected. Therefore, there is a critical need to prioritize cyber security in the automotive sector.
Several ECUs (electronic control units) with connected sensors in a car are connected over in-vehicle networks such as CAN, MOST, Ethernet, Flex Ray, and LIN. These network protocols lack the design of an information security mechanism at the beginning of their design, which makes them vulnerable to cyber-attacks such as sniffing, jamming, replay, or forgery of messages. This paper first presents a brief introduction and a list of the limitations of the original design of vehicle bus protocols. Then, the protocols for in-vehicle communication are classified based on their characteristics and usage type. Finally, various security solutions to address these limitations will be reviewed.

Keywords: Connected Vehicles, Automotive, Cybersecurity, Connectivity, CAN (Controller Area Network), Automotive Ethernet, Autonomous, V2X (Vehicle-to-Everything), Artificial Intelligence.
