ICST Transactions Preprint Middleware-based Security for Hyperconnected Applications in Future In-Car Networks

Today’s cars take advantage of powerful electronic platforms and provide more and more sophisticated connected services. More than just ensuring the role of a safe transportation mean, they process private information, industrial secrets, communicate with our smartphones, Internet and will soon host thirdparty applications. Their pervasive computerization makes them vulnerable to common security attacks, against which automotive technologies cannot protect. The transition toward Ethernet/IP-based on-board communication could be a first step to respond to these security and privacy issues. In this paper, we present a security framework leveraging local and distributed information flow techniques in order to secure the on-board network against internal and external untrusted components. We describe the implementation and integration of such a framework within an IP-based automotive middleware and provide its evaluation.
