Researchers Propose Cyber Protections Against 'Logic Bombs'

Cybersecurity researchers at Rutgers University-New Brunswick and the Georgia Institute of Technology have proposed new ways to protect 3D printed objects from stealthy "logic bombs."

3D printing, or additive manufacturing, is increasingly used to produce safety-critical products in the aerospace, automotive, and medical industries, but there currently are no trustworthy methods for verifying their integrity against adversarial pre-print design modifications.

The researchers looked into Mystique, a class of attacks on printed objects that can evade countermeasures and embed computer code, or logic bombs, through manufacturing process manipulation.

They propose two mitigation strategies to defend against Mystique in "Physical Logic Bombs in 3D Printers via Emerging 4D Techniques," presented at the ACSAC 2021, the Annual Computer Security Applications Conference.
