As the electronics that goes into a car evolves at a rapid pace and the car progresses from an isolated unit to a networked/connected unit, cars are becoming increasingly vulnerable to malicious attacks. With the current advancements such as users being able to connect their personal devices like the tablet and the cell phone to the car, access to cloud computing, car to car and car to infrastructure communications, there is nothing to stop anyone with malicious intent and with some computer-programming skills to gain access to the vehicle ECUs and take control of the vehicle. After gaining access, a hacker could control anything from say, which song plays on the radio to start or stop the engine, since all the ECUs usually share an unsecured CAN bus. Cars, thus, require security measures similar to those implemented in e-commerce solutions and personal computing devices. Presently, car manufacturers are beginning to take steps to secure networks similar to those taken by the information technology sector to lock down corporate servers. However, the current control units in vehicles are developed to address safety but not security requirements. The objective of this paper is to provide an approach for secure automotive communication - both internal and external, by designing a central unit in the vehicle. A smart gateway ECU is proposed for this purpose, which would be based on modern cryptographic mechanisms to provide authentication, integrity and confidentiality mechanisms that shall solve the vehicular security issues. The smart gateway ECU consists of an external and an in-vehicle gateway. The external gateway interfaces with the outside world and the in-vehicle gateway interconnects the ECUs in the different vehicle networks. This module would support secure APls for vehicle connectivity, which are governed by configurable security policies that act as a firewall controlling the access to the in-vehicle network. The smart gateway would additionally handle secure key storage and management.
