Today's vehicle has become a very complex good, offering performance and reliability thanks to a sophisticated network of Electronic Control Units. Each year car makers develop new automotive features for use inside and outside of the car. But improving this infrastructure each time adds new costs and overhead to the system. A promising solution resides in the use of Internet Protocol (IP) standards for both on-board and vehicle-to-X communications. With IP over Ethernet, bandwidth and system performance will increase, but so will the security risks for both passenger safety and vehicle system integrity. IP is a well-known and attack-prone technology and the car an easy prey. Communication encryption and static access controls won't be sufficient; more suitable and complex security protocols and infrastructures are required. In this technical report we present a new framework architecture for on-board security, allowing establishment of internal and external secure communication channels and secure runtime environment for automotive applications. The modularization of the framework allows protocol independency and adaptability in terms of performance and security for automotive use cases.
