Practical Information-Flow Aware Middleware for In-Car Communication

Today’s vehicles are increasingly connected to Internet, de-vices and integrate more and more electronic components.More than just ensuring their passengers’ safety, which re-mains nevertheless one of their main objectives, cars haveto deal with private information and encounters the samesecurity issues as traditional computers. Until recently, au-tomotive technologies allowed very little space for security,but the transition towards full Ethernet-based on-board net-work will change this situation. In this paper, we present so-lutions for decentralized information flow control in order toenhance the security and privacy level of the car data man-agement. We describe the implementation of these mecha-nisms in an automotive middleware and propose its evalua-tion.
