Secure Logic Locking with Strain-Protected Nanomagnet Logic

2021 58th ACM/IEEE Design Automation Conference (DAC), 2021
Prevention of integrated circuit counterfeiting through logic locking faces the fundamental challenge of securing an obfuscation key against both physical and algorithmic threats. Previous work has focused on strengthening the logic encryption to protect the key against algorithmic attacks, but failed to provide adequate physical security. In this work,

On the Security of Sequential Logic Locking Against Oracle-Guided Attacks

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2023
The Boolean satisfiability (SAT) attack is an oracle-guided attack that can break most combinational logic locking schemes by efficiently pruning out all the wrong keys from the search space.

KRATT: QBF-Assisted Removal and Structural Analysis Attack Against Logic Locking

Design, Automation and Test in Europe, 2023
This paper introduces KRATT, a removal and structural analysis attack against state-of-the-art logic locking techniques, such as single and double flip locking techniques (SFLTs and DFLTs).

LOOPLock: Logic Optimization-Based Cyclic Logic Locking

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2020
SAT Attack, CycSAT, and Removal Attack have demonstrated their abilities to break most existing logic locking methods. In this article, we propose a new cyclic logic locking method to invalidate these attacks simultaneously. Our main intention is to create noncombinational cycles to lock a circuit.

DeepAttack: A Deep Learning Based Oracle-less Attack on Logic Locking

International Symposium on Circuits and Systems, 2023
Logic locking is one of the most promising design-for-trust technique for protecting intellectual property from reverse engineering, IP piracy, and modification throughout the electronic supply chain.

RTLock: IP Protection using Scan-Aware Logic Locking at RTL

Design, Automation and Test in Europe, 2023
Conventional logic locking techniques mainly focus on gate-level netlists to combat IP piracy and IC overproduction. However, this is generally not sufficient for protecting semantics and behaviors of the design.

Importance of Logic Locking Attacks in Hardware Security

2023 International Conference on Intelligent Data Communication Technologies and Internet of Things (IDCIoT), 2023
A rise in the number and devastating capability of hardware-based assaults has brought attention to the necessity of protecting the hardware root of trust alongside improvements in power, cost, performance, and reliability.

SCOPE: Synthesis-Based Constant Propagation Attack on Logic Locking

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2021
Hardware intellectual property (IP) piracy and misuse have introduced new challenges in the semiconductor industry as untrusted parties in the IP’s life cycle may clone, reverse-engineer, or extract important design secrets from an IP.

Evolution of logic locking

2017 IFIP/IEEE International Conference on Very Large Scale Integration (VLSI-SoC), 2017
The globalization of integrated circuit (IC) supply chain and the emergence of threats, such as intellectual property (IP) piracy, reverse engineering, and hardware Trojans, have forced semiconductor companies to revisit the trust in the supply chain. Logic locking is emerging as a popular and effective countermeasure against these threats.

Logic Locking Induced Fault Attacks

2020 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2020
Logic locking has been presented in the past as a solution to avoid overproduction or product piracy. All solutions so far assume or rely on the protection of the correct locking key. This paper does not target the break of locking schemes but looks at another highly critical security risk which comes with modified locking keys: The enabling of fault ...
