Hardware-Assisted Security in Electronic Control Units: Secure Automotive Communications by Utilizing One-Time-Programmable Network on Chip and Firewalls

摘要: With emerging smart automotive technologies, vehicle-to-vehicle communications, and software-dominated enhancements for enjoyable driving advanced driver assistance systems, the complexity of providing guarantees in terms security, trust, privacy a modern cyber-enabled system is significantly elevated. New threat models emerge that require efficient system-level countermeasures. This article introduces synergies between on- off-chip networking techniques to ensure secure execution environments electronic control units. The proposed mechanisms consist hardware firewalling on-chip network physical isolation, whose are combined with system-wide cryptographic controller area (CAN)-bus communications provide authentication confidentiality.
