The Problem: Modern vehicles contain dozens of ECUs exchanging thousands of signals across CAN, LIN, Ethernet, and FlexRay buses — yet most Cybersecurity Management Systems (CSMS) treat the network as a black box. This session presents a signal-level security framework that bridges the gap between UNECE R155 compliance and real engineering practice.
Our Approach: We introduce a Network Communication Matrix that maps every signal to its security attributes — authentication, freshness, access control, and traceability — creating a unified engineering reference from design through production. The framework integrates COVESA VSS/VISS data models, AUTOSAR Secure Onboard Communication (SecOC), and ISO/SAE 21434 processes into a cohesive toolchain.
What You’ll Learn: Attendees will learn how to transform abstract regulatory requirements into concrete, auditable engineering artifacts — and why signal-level granularity is the missing link between compliance documentation and vehicle-level cybersecurity.
