Reevaluating Graph-Neural-Network-Based Runtime Prediction of SAT-Based Circuit Deobfuscation

Cryptography, 2022
Logic locking is a technique that can help hinder reverse-engineering-based attacks in the IC supply chain from untrusted foundries or end-users. In 2015, the Boolean Satisfiability (SAT) attack was introduced.

ProbLock: Probability-based Logic Locking

CoRR, 2021
Integrated circuit (IC) piracy and overproduction are serious issues that threaten the security and integrity of a system. Logic locking is a type of hardware obfuscation technique where additional key gates are inserted into the circuit. Only the correct key can unlock the functionality of that circuit otherwise the system produces the wrong output ...

Defense-in-depth: A recipe for logic locking to prevail [PDF]

Integration, 2020
Logic locking has emerged as a promising solution for protecting the semiconductor intellectual Property (IP) from the untrusted entities in the design and fabrication process. Logic locking hides the functionality of the IP by embedding additional key-gates in the circuit.
