An intrusion detection method for securing in-vehicle CAN bus

Controller area network (CAN) bus has become the most used protocol in automotive network since its robustness and efficiency. However, CAN bus does not have enough security prosperities to protect the whole automotive system even to protect its network. So, security mechanism to protect CAN bus became an emergency need. One of the efficient methods for securing CAN bus, is Intrusion Detection System (IDS). In this work, a simple intrusion detection method for CAN bus is proposed. Our algorithm does not require any modification in standard procedure of CAN bus nor to be implemented in each calculators of network.
