Secure Logic Locking with Strain-Protected Nanomagnet Logic
2021 58th ACM/IEEE Design Automation Conference (DAC), 2021Prevention 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,

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.

Attacks on Logic Locking Obfuscation Techniques
2021 IEEE International Conference on Consumer Electronics (ICCE), 2021Logic Locking is a relatively new obfuscation technique that is at the forefront of preventing IP theft, piracy, overproduction, and counterfeiting of chips made in contracted foundries. As logic locking develops and new gate insertion techniques are created, their resilience to attacks must be evaluated to know their true effectiveness. In this paper,

On Improving the Security of Logic Locking
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2016Due to globalization of integrated circuit (IC) design flow, rogue elements in the supply chain can pirate ICs, overbuild ICs, and insert hardware Trojans. EPIC locks the design by randomly inserting additional gates; only a correct key makes the design to produce correct outputs.

Trustworthy Hardware Design with Logic Locking
2021 IFIP/IEEE 29th International Conference on Very Large Scale Integration (VLSI-SoC), 2021As the designated root of trust, hardware is undoubtedly the most critical layer to security in modern electronic systems. Protecting its integrity throughout the integrated circuit supply chain is of paramount importance. Logic locking has become a prominent tool to safeguard hardware against malicious design modifications.

On the Limitations of Logic Locking the Approximate Circuits
2022 Asian Hardware Oriented Security and Trust Symposium (AsianHOST), 2022Approximate Computing (AxC) is an emerging architectural paradigm, which promises improvements in area, performance or power consumption at the expense of limited and tolerable inaccuracies of computations. Circuits designed in typical AxC-friendly applications, such as neural network accelerators, visual computing and high-bandwidth communication, are

Logic Locking Induced Fault Attacks
2020 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2020Logic 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 ...

Design and Analysis of Logic Locking Techniques
2021 IFIP/IEEE 29th International Conference on Very Large Scale Integration (VLSI-SoC), 2021The skyrocketing cost of integrated circuit (IC) manufacturing has forced the majority of enterprises to shift to fabless operation. IC design is often outsourced to foreign fabrication laboratories to reduce time and cost However, as a flip-side, it has introduced various hardware security concerns at different stages in the supply chain, namely, IP ...

A Glitch Key-Gate for Logic Locking
2019 32nd IEEE International System-on-Chip Conference (SOCC), 2019Logic locking is a technique used for intellectual property protection. An effective attacking method based on satisfiability (SAT) algorithm, known as SAT attack, was proposed to decrypt an encrypted design successfully. To strengthen logic locking, this paper proposes a glitch-based logic locking method designed for sequential circuits.

Temporal Logic Verification of Lock-Freedom
2010Lock-free implementations of data structures try to better utilize the capacity of modern multi-core computers, by increasing the potential to run in parallel. The resulting high degree of possible interference makes verification of these algorithms challenging. In this paper we describe a technique to verify lock-freedom, their main liveness property.
