cosimulation testbed

A cosimulation testbed is an advanced testing environment that integrates multiple, independent simulators from different domains to run synchronously and exchange data in real-time. Originating from complex systems engineering, it addresses the limitation of a single simulation tool. In automotive cybersecurity, it is used for verification and validation as required by ISO/SAE 21434, testing complex interactions between in-vehicle networks, powertrains, and external communications. The core technology often relies on the Functional Mock-up Interface (FMI) standard (ISO 23492), which defines a unified interface for model exchange and co-simulation, ensuring interoperability between tools from different vendors. Within a risk management framework, this platform serves as a key early-stage verification tool, enabling the cost-effective, efficient, and safe replication of high-risk cyberattack scenarios to identify systemic vulnerabilities before Hardware-in-the-Loop (HIL) testing.

In enterprise risk management, a cosimulation testbed is a critical tool for implementing 'Security by Design.' The implementation process includes three key steps: 1. **Architecture Definition & Tool Selection**: Based on a TARA (per ISO/SAE 21434), identify key test scenarios and define the simulation architecture, selecting appropriate tools (e.g., Vector CANoe, MATLAB/Simulink, OMNeT++) for each subsystem. 2. **Model Development & Integration**: Package each subsystem as a Functional Mock-up Unit (FMU) using the FMI standard and configure data exchange interfaces and synchronization mechanisms within the platform. 3. **Automated Testing & Analysis**: Design and execute automated cyberattack test cases, such as spoofing ISO 15118 communication protocols. Leading automotive suppliers use this approach to identify over 80% of potential security vulnerabilities during development, ensuring 100% compliance with regulations like UN R155 at launch and reducing the overall validation cycle by approximately 30%.

Taiwanese enterprises face three main challenges: 1. **High Toolchain Costs & Technical Barriers**: The required software licenses are expensive, and integrating them demands scarce multi-disciplinary talent. Mitigation involves a hybrid strategy, starting with open-source tools and engaging expert consultants for knowledge transfer. 2. **Lack of Standardized Reference Models**: As part of the supply chain, firms often lack access to complete vehicle models from OEMs. The solution is to collaborate with research institutes like ARTC to develop localized reference models and focus initially on modeling their own product's interface behavior. 3. **Gap Between Test Cases & Real-world Threats**: Internal teams may lack up-to-date threat intelligence. To overcome this, enterprises should subscribe to threat intelligence feeds and partner with cybersecurity firms to convert real-world attacks into simulation scripts, ensuring test cases remain relevant and effective.
