Integrated 10G Automotive Ethernet Architectures for Secure, EMC-Resilient ADAS and V2X Systems: A Multi-Protocol, Post-Quantum-Aware Framework

Abstract

Background: Modern vehicles increasingly rely on high-bandwidth, low-latency communication fabrics to support Advanced Driver-Assistance Systems (ADAS), camera and sensor subsystems, and vehicle-to-everything (V2X) services. The migration toward 10 Gigabit Automotive Ethernet (10G AE) raises technical challenges across electromagnetic compatibility (EMC), multi-protocol integration, cyber resilience, and the software/hardware coordination of electronic control units (ECUs) and inertial measurement units (IMUs). Simultaneously, optical and high-speed digital transmission research offers perspectives on managing error rates and link stability. This paper synthesizes evidence from Ethernet-for-automotive analyses, V2X gateway implementations, ADAS ECU/IMU roles, EMC mitigation case studies, and post-quantum cryptography considerations to propose an integrated architecture and evaluation narrative. (Ioana et al., 2022; Kern, 2013; Katari et al., 2024; KARIM, 2025; Prest et al., 2017).

 Methods: We conduct a methodical cross-domain synthesis of published engineering analyses and experimental work, mapping known technical constraints onto a cohesive design space for 10G Automotive Ethernet deployments within ADAS and V2X ecosystems. We organize the synthesis by physical layer concerns (EMC, shielding, cabling), link and protocol conversion (multi-protocol gateways), ECU/IMU data flows and timing, error control strategies, and cryptographic readiness including post-quantum algorithms. (Ioana et al., 2022; KARIM, 2025; A. Naughton et al., 2012; Prest et al., 2017).

 Results: The integrated framework emphasizes: (1) hybrid shielding and PCB layout validated EMC approaches for camera and lighting control to minimize 10G interference risks; (2) multi-protocol gateway designs that preserve timing and determinism necessary for ADAS sensor fusion; (3) a layered error-management strategy incorporating forward error correction learning from optical comms studies; and (4) a migration path for incorporating post-quantum cryptographic primitives such as FALCON into vehicular keying infrastructures. (KARIM, 2025; Ioana et al., 2022; Brandonisio et al., 2017; Prest et al., 2017).

 Conclusion: Transitioning to 10G AE in safety-critical vehicles requires a systems-level approach that integrates EMC-aware hardware design, protocol bridging that preserves deterministic behaviors, robust error mitigation drawing from optical network research, and anticipatory cryptographic upgrades. We identify research priorities and practical engineering guidelines to operationalize this transition while maintaining ADAS safety and V2X security requirements. (Kern, 2013; Katari et al., 2024).
