Protecting In-Vehicle Services: Security-Enabled SOME/IP Middleware

摘要

With every generation, vehicles are becoming smarter and more oriented toward information and communications technology (ICT). However, computerization is posing unforeseen challenges in a sector for which the first goal must be safety: car hacking has been shown to be a real threat. This article presents a novel mechanism to provide improved security for applications executed in the vehicle based on the principle of defining exactly who can talk to whom. The proposed security framework targets Ethernet-based com - munications and is tightly integrated within the emerging Scalable service-Oriented MiddlewarE over IP (SOME/IP) middleware. No complex configurations are needed: simple high-level rules, clearly stating the communications allowed, are the only element required to enable the security features. The designed solution has been implemented as a proof of concept (PoC) inside the vsomeip stack to evaluate the validity of the approach proposed: experimental measurements confirm that the additional overhead introduced in end-to-end communication is negligible.
