-Aligning requirements in automotive security standardisation-

Francesca Romana Forestieri･Gil Bernabeu (GlobalPlatform)･Jorge Wallace Ruiz (Dekra)

GlobalPlatform is bringing proven, standardized security solutions—deployed at scale across industries—into automotive, working with OEMs and Tier suppliers to deliver new engineering guidance that directly responds to SAE J3101 Hardware Protected Security Environments. Our work produces: (1) standardized platform architecture and API specifications for isolated execution environments, (2) a Trusted Application model enabling both portable standardized functions and controlled OEM/supplier-specific apps, and (3) SESIP Automotive Security Profiles under development including J3101 components, ECUs, and CMOS image sensors. SESIP adds measurable, reusable certification assets for procurement comparability and reduced late-stage testing. JSAE engagement is invited.

Trusted Execution Environments in Automotive Real-Time Systems

Real-time environments demand efficient, resource-saving implementation, especially in automotive systems where cost-optimized control units are crucial. Modern vehicles increasingly rely on networking, online functions, and software updates, raising requirements for secure communication and data storage. Trusted Execution Environments (TEEs) address these security needs. This article explores current TEE approaches, highlighting their advantages and disadvantages, and outlines requirements for future TEEs in automotive real-time environments. It presents a concept that meets these requirements, ensuring secure control units and communication in increasingly connected vehicles, while maintaining efficiency and cost-effectiveness.

Crypto-Agility in Automotive Real-Time Systems in Context of Post-Quantum-Cryptography

Philipp Jungklass･Carolina Pelka･Tim Kaiser･Claude-Pascal Stoeber-Schmidt (IAV)･Dennis Kengo Oka (IAV Japan)･Marco Siebert (IAV)･Takuya Nigoro (IAV Japan)

Quantum computer advances necessitate cryptographic agility, as they efficiently solve asymmetric cryptography problems, requiring algorithm replacement for security. Crypto-agility is crucial for systems receiving software updates over years, like Software Defined Vehicles (SDVs), which expand functionality through software. Resource-limited systems in real-time applications using microcontrollers with hardware-supported cryptographic algorithms face challenges, as hardware accelerators can't be updated. This article presents a concept for updating Electronic Control Units (ECUs) in real-time applications on the AUTOSAR Classic Platform. It implements and evaluates all NIST-standardized post-quantum algorithms on two generations of automotive microcontrollers.
