Expanding In-Cone Obfuscated Tree for Anti SAT Attack

Design, Automation and Test in Europe, 2023
Logic locking is a hardware security technology to protect circuit designs from overuse, piracy, and reverse engineering. It protects a circuit by inserting key gates to hide the circuit functionality, so that the circuit is functional only when a ...

JANUS-HD: Exploiting FSM Sequentiality and Synthesis Flexibility in Logic Obfuscation to Thwart SAT Attack While Offering Strong Corruption

Design, Automation and Test in Europe, 2022
Logic obfuscation has been proposed as a counter-measure towards chip counterfeiting and IP piracy by obfuscating circuit designs with a key-controlled locking mechanism.

A Comprehensive Test Pattern Generation Approach Exploiting the SAT Attack for Logic Locking

IEEE transactions on computers, 2022
The need for reducing manufacturing defect escape in today's safety-critical applications requires increased fault coverage. However, generating a test set using commercial automatic test pattern generation (ATPG) tools that lead to zero-defect escape is

SATAM: A SAT Attack Resistant Active Metering Against IC Overbuilding

IEEE Transactions on Emerging Topics in Computing, 2022
In the horizontal semiconductor business model, a foundry can tamper or overbuild the integrated circuits (ICs) while the IC owner knows nothing about it. Active IC metering scheme has been proposed to solve this problem by enabling IC owners to uniquely

Enhancing SAT-Attack Resiliency and Cost-Effectiveness of Reconfigurable-Logic-Based Circuit Obfuscation

International Symposium on Circuits and Systems, 2021
Logic locking is a well-explored defense mechanism against various types of hardware security attacks. Recent approaches to logic locking replace portions of a circuit with reconfigurable blocks such as look-up tables (LUTs) and switch boxes (SBs) to ...

SAT-attack Resilience Measure for Access Restricted Circuits

ACM Great Lakes Symposium on VLSI, 2021
With the recent introduction of techniques to restrict scan chain access, a new class of deobfuscation problems emerge, in which the threat model, although similar to deobfuscation of a logic locked circuit, forms a novel class of attack.

NNgSAT: Neural Network guided SAT Attack on Logic Locked Complex Structures

2020 IEEE/ACM International Conference On Computer Aided Design (ICCAD), 2020
The globalization of the IC supply chain has raised many security threats, especially when untrusted parties are involved. This has created a demand for a dependable logic obfuscation solution to combat these threats.
