Abstract
The advanced manufacturing industry (AMI) faces many unique challenges from the cyber-physical domain. Security threats are originated from two integral parts: software and hardware. Over the past decade, software security has been addressed extensively, but hardware security has not received enough attention. This work analyzes the security vulnerabilities of typical electronic devices deployed to AMI and proposes three attack models for sensing nodes, local storage and processing edge devices, and wired/wireless communication interfaces, respectively. Practical security attacks on hardware are demonstrated in this work to inspire the development of feasible countermeasures against hardware Trojans, fault injection attacks, and external signal interference. Moreover, this work highlights the unique security challenges posed by advanced manufacturing applications. To mitigate those security attacks in AMI, this work suggests guidelines for the defense method design that can effectively protect the hardware in AMI.
