Design Principles
"Cyber-physical system security can be enhanced by modeling and mitigating information leakage at the design and manufacturing planning stages."
In increasingly interconnected manufacturing environments, the physical manifestations of digital processes (like acoustic or power emissions) can inadvertently reveal sensitive design or operational data. By modeling and accounting for these leakage pathways within the CAM software, designers and engineers can make informed decisions about machine parameters or product designs to enhance security without necessarily requiring costly hardware modifications.

Paragraph starter
The integration of cyber-physical systems in manufacturing introduces novel security challenges, particularly concerning information leakage through physical side-channels. Research by Chhetri et al. (2018) demonstrates that by developing leakage-aware Computer-Aided Manufacturing (CAM) tools, it is possible to proactively mitigate these risks. Their methodology, implemented on an FDM system, achieved significant reductions in mutual information across acoustic, power, magnetic, and vibration side-channels, thereby decreasing the success rate of potential attackers and hindering the reconstruction of sensitive design details. This highlights the potential for CAM systems to serve as a crucial layer of defense against intellectual property theft and unauthorized access in modern manufacturing environments.
