Controller Area Network Insecurity

Keywords Controller Area Network CAN, autonomous systems, intrusion, security, vulnerability andthreat modeling. 1. Introduction. As the number of electronic features embedded in modern cars continues to increase, cars can now be compared to advanced computers operating with numerous digital nodes . These nodes provide drivers with a wide

Keywords Internet of Vehicles IoV, Controller Area Network CAN, security evaluation tool. 1. Introduction. The development of sensors and communication technology promotes the evolution of the Internet of Things IoT. The number of devices connected to the Internet increases rapidly around us, which constructs a network called IoT.

Controller Area Network CAN is the dominant communication standard for intra-vehicle communications in automobiles. The CAN protocol is designed to be light-weight in order to increase speed and efficiency. However, this severely limits the protocol's ability to support any kind of security countermeasures. Some of the devices that utilize CAN lack the resources to perform the required

The Controller Area Network, commonly referred to as Controller Area Network CAN bus, is a serial standard for field buses that is primarily employed in the automotive industry. It was introduced in the 1980s by Robert Bosch as a means to connect various electronic control units ECUs.

The controller area network CAN protocol, used in many modern vehicles for real-time inter-device communications, is known to have cybersecurity vulnerabilities, putting passengers at risk for

Controller Area Network CAN is the widely used In-vehicle networking when seen from a normal point of view, CAN is really powerful in transmitting all the critical and non-critical systems data to all the ECU's Electronic Controller Unit and other units. So, when it comes down to the understanding of CAN systems, it becomes a bit tedious.

We propose a security mechanism to help prevent cyber-attacks masquerade and replay in vehicles with architecture based on Controller Area Network CAN. We focus on CAN as it will likely continue being used in upcoming in-vehicle architectures. The CAN protocol contains no direct support for secure communications. Retrofitting the protocol with security mechanisms poses several challenges
