Controller Area Network (CAN) is a well designed communications bus for sending and receiving short real-time control messages at speeds of up to 1Mbit/sec. One of the perceived drawbacks to CAN has been the inability to bound accurately the worst-case response time of a given message (i.e. the longest time between queueing the message and the message arriving at the destination processors). Th...

Now-a-days, as computerization of automotive increases, the need for more/advanced electronic control units (ECUs) is growing. Vehicles are increasingly behaving like computers with wheels. Due to the abundance use of ECUs in cars, electronic system design is becoming complicated day by day. As a consequence, information processing in such complex systems faces interruptions. Therefore, there i...

Controller Area Network (CAN) is a digital communications bus used by the automotive industry for invehicle networks. Research from the Real-Time Systems Group at the University of York introduced techniques that enable CAN to operate under high loads (approx. 80% utilisation) while ensuring that all messages meet their deadlines. The research led directly to the development of commercial produ...

Up until now, we’ve considered our embedded control system to be self-contained: an algorithm implemented in software resident on a single microprocessor, communicating with its environment through sensors and actuators via peripheral devices such as an analog-to-digital converter. In fact, many embedded systems are distributed, consisting of multiple microprocessors communicating over one or m...

Controller Area Network is normally used in eventtriggered communication systems. These are known for not supporting composability with respect to the system temporal behavior. When using a time-triggered communication paradigm, such composability is achieved. However, common time-triggered systems rely on static message scheduling which compromises system flexibility. In this paper the authors...

Controller Area Network (CAN) is a communication bus that has no cryptographic protection against malicious adversaries. Once isolated, the environments in which CAN operates are now opened to intruders and assuring broadcast authentication becomes a concern. To achieve this, public key primitives are not a solution because of the computational constraints, but symmetric primitives can be used ...

It is widely known that Control Area Networks (CAN) are used in real-time, distributed and parallel processing which cover manufacture plants, humanoid robots, networking fields, etc., In applications where wireless conditions are encountered it is convenient to continue the exchange of CAN frames within the Wireless CAN (WCAN). The WCAN considered in this research is based on wireless token ri...

The existing automotive Controller Area Network (CAN) is vulnerable. The absence of sender verification in its communication means that an attacker acting as a node on its network will be treated like a legitimate node that has always been present, allowing attackers to transmit and receive messages freely. This paper proposes a system that will allow nodes using CAN to identify legitimate mess...
