摘要：Nowadays with the help of advanced technology, modern vehicles are not only made up of mechanical devices
but also consist of highly complex electronic devices and connections to the outside world. There are around 70 Electronic
Control Units (ECUs) in modern vehicle which are communicating with each other over the standard communication
protocol known as Controller Area Network (CAN-Bus) that provides the communication rate up to 1Mbps. There are
different types of in-vehicle network protocol and bus system namely Controlled Area Network (CAN), Local
Interconnected Network (LIN), Media Oriented System Transport (MOST), and FlexRay. Even though CAN-Bus is
considered as de-facto standard for in-vehicle network communication, it inherently lacks the fundamental security features
by design like message authentication. This security limitation has paved the way for adversaries to penetrate into the
vehicle network and do malicious activities which can pose a dangerous situation for both driver and passengers. In
particular, nowadays vehicular networks are not only closed systems, but also they are open to different external interfaces
namely Bluetooth, GPS, to the outside world. Therefore, it creates new opportunities for attackers to remotely take full
control of the vehicle. The objective of this research is to survey the current limitations of CAN-Bus protocol in terms of
secure communication and different solutions that researchers in the society of automotive have provided to overcome the
CAN-Bus limitation on different layers.
