Editor’s note: As a type of invasive physical attacks, probing attacks are able to access and directly monitor security critical nets of an IC and extract sensitive information. In this paper, the authors summarize the state-of-the-art probing and anti-probing technologies and their challenges, and discuss the opportunities in the relevant research. —Yiran Chen, Duke University
Microprobing attacks against integrated circuits (IC) for security critical applications have become a serious concern. With the help of modern circuit editing techniques, an attacker could remove layers of materials and expose wires carrying security critical information for probing. Existing protection methods use active shielding to detect such attacks. However, this technique has been proven to...
