Strategy for ensuring in-vehicle infotainment security

In-vehicle networks were initially developed to operate in a closed environment and thus their security has not been concerned. However, growing attention has been paid to the convenience and entertainment value of vehicles, and thus automakers are integrating general entertainment devices into vehicles, which brings about the problem of information security. In this paper, the structure of secondary defense system was used to obstruct the Internet and autobody inner in-vehicle networks such as CAN and LIN. We built a strategy ensuring in-vehicle gateway security and an in-vehicle information software system.
