An Automotive Reference Testbed with Trusted Security Services

While research in the field of automotive systems inclined past years towards technologies such as Vehicle-to-Everything (V2X) or Connected and Automated Vehicle (CAV), underlying system security still plays a crucial role assuring trust safety. The work at hand tackles issue by designing multi-service specially tailored for in-vehicle networks. proposed trusted services leverage Trusted Platform Module (TPM) to store secrets manage exchange cryptographic keys. To showcase how can be implemented network, Reference TestBed (RTB) was developed. In RTB, encryption authentication keys are periodically exchanged, data is sent authenticated, network monitored Stateful Firewall Intrusion Detection System (SF/IDS), events logged reported. A formal individual multi-protocol analysis conducted demonstrated feasibility from theoretical point view. Two distinct scenarios were considered present workflow interaction between services. Lastly, performance measurements on reference hardware provided.
