SESSION VS 2-6 WIP: The Feasibility of High-performance Message Authentication in Automotive Ethernet Networks

Modern vehicles are increasingly connected systems that expose a wide variety of security risks to their users. Message authentication prevents entire classes of these attacks, such as message spoofing and electronic control unit impersonation, but current in-vehicle networks do not include message authentication features. Latency and throughput requirements for vehicle traffic can be very stringent (100 Mbps in cases), making it difficult to implement message authentication with cryptography due to the overheads required. This work investigates the feasibility of implementing cryptography-based message authentication in Automotive Ethernet networks that is fast enough to comply with these performance requirements. We find that it is infeasible to include Message Authentication Codes in all traffic without costly hardware accelerators and propose an alternate approach for future research to minimize the cost of authenticated traffic.

Symposium on Vehicle Security and Privacy (VehicleSec) 27 February 2023 in San Diego, California.

ABOUT VEHICLESEC 2023
The Inaugural Symposium on Vehicle Security and Privacy (VehicleSec 2023) is built upon the continuous four-year growth of the AutoSec (Automotive and Autonomous Vehicle Security) Workshop with the NDSS Symposium. This brand new symposium aims at bringing together an audience of university researchers, scientists, industry professionals, and government representatives to contribute new theories, technologies, and systems on any security/privacy issues related to vehicles (e.g., ground, aerial, underwater, space), their sub-systems (e.g., in-vehicle networks, autonomy, connectivity, human-machine interfaces), supporting infrastructures (e.g., transportation infrastructure, charging station, ground control station), and related fundamental technologies (e.g., sensing, control, AI/ML/DNN, real-time computing, edge computing, location service, simulation, digital twin, multi-agent protocol/system design, and human-machine interaction).

VehicleSec 2023 is a hybrid event, co-located with the Network and Distributed System Security Symposium (NDSS) 2023.
