Abstract
The modern car comprises dozens of Electronic Control Units (ECUs) running several hundred MBs of code, alongside sophisticated dashboards with integrated wireless communications. While this has brought upon a wide range of advantages and integrated features, it also exposed modern vehicles to significant threats. As a response, we developed a generic scheme for distributing keys between ECUs. The approach leverages the Trusted Platform Module (TPM) 2.0 standard to provide a tamper-proof cryptographic co-processors capable of executing cryptographic operations in a secure manner. The scheme aims at empowering ECUs to leverage state of the art cryptographic techniques by adopting recent technological advances such as the TPM. Implementation details and analysis demonstrate the feasible application of the approach in the context of the modern vehicle.
