Abstract :

                 Vehicle-IT convergence technology is a rapidly rising paradigm of modern vehicles, in which an electronic control unit (ECU) is used to control the vehicle electrical systems, and the controller area network (CAN), an in-vehicle network, is commonly used to construct an efficient network of  ECUs. Unfortunately, security issues have not been treated properly in CAN, although CAN control messages could be life-critical. With the appearance of the connected car environment, in-vehicle networks (e.g., CAN) are now connected to external networks (e.g., 3G/4G mobile networks), enabling an adversary to perform a long-range wireless attack using CAN vulnerabilities. In this paper we show that a long-range wireless attack is physically possible using a real vehicle and malicious smart phone application in a connected car environment. We also propose a security protocol for CAN as a countermeasure designed in accordance with current CAN specifications. We evaluate the feasibility of the proposed security protocol using CAN and a lpc2148 microcontroller. Our results show that the proposed security protocol is more efficient than existing security protocols with respect to authentication delay and communication load..

                      The system consists of microcontroller, CAN controller and parameters of VEHICAL. Microcontroller is the key element in processing module which keeps on monitors the VEHICAL parameters. In the VEHICAL temperature sensor, MEMS sensor and are connected to monitor the physical parameter of the VEHICLE. CAN controller is used to communicate between the wind turbine and the database. For every particular amount of time, microcontroller pre-processes sensed data and it will update the parameter values to the central database. RS232 is used for serial communication between the PC and the CAN Bus. CAN interface module is used to communicate the monitored parameters between the VEHICLE and the control centre. The CAN interface module consists of three components CAN Transceiver (MCP 255 1), CAN Controller (MCP 25 10), DSPIC. CAN transceiver is required to shift the voltage levels of the microcontroller to those appropriate for the CAN bus.
