Automotive architectures are constantly evolving to offer new features to end-users. Safety is critical, and cannot, in modern connected architectures, be achieved without strong cybersecurity. This paper proposes an advanced model of architecture supporting efficient cy-bersecurity properties. The global approach is an open way to include cybersecurity components that dynamically enforce the requested properties in a distributed manner. It supports heterogeneous software and hardware components and allows detection of malicious or unsafe behaviors. The paper illustrates the ability to integrate such a model into a standardized automotive middleware such as SOME/IP.
