The automotive industry’s shift toward software-defined vehicles (SDVs) replaces traditional hardware isolation with complex, interconnected software ecosystems. While this evolution accelerates innovation, it significantly expands the cyber-attack surface. Interoperability serves as the essential foundation for automotive resilience, requiring standardized 3GPP communication protocols and cross-platform security frameworks to protect safety-critical systems. By harmonizing diverse software layers, manufacturers can maintain seamless connectivity without compromising robust token-based cybersecurity. Prioritizing unified, interoperable security standards ensures long-term scalability and safety, providing a roadmap for securing the future of mobility against increasingly sophisticated and dynamic digital threats.
