Introduction to the Special Issue on Security and Privacy in Safety-Critical Cyber-Physical Systems
Cyber-Physical Systems (CPS) are the backbone of modern infrastructure, from autonomous vehicles to industrial control, merging computational and physical processes. This special issue highlights the critical and complex challenges of securing these safety-critical systems, particularly with the rise of AI and machine learning. Traditional security measures are insufficient due to real-time constraints, hardware limitations, and the unique threat landscape posed by interconnectedness. The research presented here offers an interdisciplinary approach, drawing from various fields to develop robust solutions that ensure not only confidentiality, integrity, and availability but also real-time responsiveness and resilience against sophisticated cyber threats. For enterprises, understanding these advancements is crucial for protecting operations, maintaining safety, and safeguarding sensitive data in an increasingly digital and automated world.

Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
Security under Strict Operational Limits
This category addresses the fundamental challenge of integrating security into CPS while adhering to their stringent real-time, energy, and performance constraints. Research focuses on techniques like secure DNN inference in trusted enclaves, real-time diagnostics for hardware attacks on ML models in edge devices, and reconfigurable scheduling frameworks that maintain real-time guarantees even under cyberattacks.
Enterprise Application: Ensures that your critical industrial automation, medical devices, and autonomous systems operate reliably and securely, even when facing sophisticated threats or resource limitations. This prevents costly downtime and maintains safety compliance.
Hardening AI/ML Against Adversarial Attacks
As AI and machine learning become integral to CPS functions like intrusion detection and predictive control, new vulnerabilities emerge. Papers in this section explore how to build ML models that are robust against adversarial inputs and manipulation, with applications in smart grids, vehicular networks (V2X), and automotive systems (CAN-bus IDS). Solutions include adversarial training and GAN-based detection frameworks.
Enterprise Application: Protects your AI-driven decision-making processes in vital systems from manipulation, ensuring the integrity of anomaly detection, predictive maintenance, and autonomous control, thereby safeguarding operations and preventing catastrophic failures.
Securing Core Control Logic and Time Synchronization
This area delves into the foundational security aspects of CPS: the integrity of control models and the reliability of time synchronization protocols. Research identifies novel stealthy control-layer attacks that exploit system vulnerabilities and proposes countermeasures like randomized sampling. It also introduces methods for securing precision time protocols against path-based delay attacks, crucial for synchronized distributed systems.
Enterprise Application: Fortifies the very bedrock of your CPS operations. By securing control loops and precise timing, it prevents subtle, undetectable attacks that could lead to operational instability, data corruption, or severe safety incidents, especially in distributed critical infrastructures.

Case Study: Securing Next-Gen Smart Manufacturing Facilities
A global manufacturing leader faced escalating cyber threats to its highly automated production lines, which rely heavily on interconnected robots, IoT sensors, and AI-driven predictive maintenance. Implementing principles from this special issue, the company adopted a framework for trusted real-time scheduling for critical control tasks (inspired by "RESCUE"), developed robust anomaly detection for energy consumption using adversarial training ("Mitigating Over-Generalization"), and secured its internal time synchronization protocols to prevent subtle manipulation ("Securing the Precision Time Protocol"). This comprehensive approach led to a 20% reduction in production downtime caused by cyber incidents and significantly improved compliance with new industry standards for operational technology security.
