Hardware Security in Advanced Manufacturing

More and more digitized techniques and network connectivity are deployed to advanced manufacturing to enable remote system monitoring and automated production; however, this trend also leads to the traditional assumption of security in manufacturing not holding true any longer. For instance, the option of remote access makes advanced manufacturing infrastructures vulnerable to various security attacks from physical devices to cyberspace. Existing literature that addresses the attacks in advanced manufacturing is mainly at the network level. In this work, we study the role of hardware security in the process of advanced manufacturing. More specifically, our analysis focuses on the security vulnerability of sensors, local data processing nodes, and the interface implementation for standardized communication protocols. Unique attack examples such as hardware Trojan, interface sniffing, and fraudulent data injection attacks are provided in this work to highlight the unique challenges of attack detection and mitigation in advanced manufacturing.
