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.

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.

Mitigating SAT Attack on Logic Locking

Lecture Notes in Computer Science, 2016
Logic locking is a technique that has been proposed to protect outsourced IC designs from piracy and counterfeiting by untrusted foundries. A locked IC preserves the correct functionality only when a correct key is provided. Recently, the security of logic locking is threatened by a new attack called SAT attack, which can decipher the correct key of ...

Keynote: A Disquisition on Logic Locking

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2020
The fabless business model has given rise to many security threats, including piracy of intellectual property (IP), overproduction, counterfeiting, reverse engineering (RE), and hardware Trojans (HT). Such threats severely undermine the benefits of the fabless model.

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,

Thwarting All Logic Locking Attacks: Dishonest Oracle With Truly Random Logic Locking

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2021
While logic locking is a promising defense to protect hardware designs, many attacks have been shown to undermine its security by retrieving the secret key. All the powerful attacks rely on a working chip, i.e., an oracle, and in particular, heavily use the test access.

Trustworthy Hardware Design with Logic Locking

2021 IFIP/IEEE 29th International Conference on Very Large Scale Integration (VLSI-SoC), 2021
As 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.

Attacks on Logic Locking Obfuscation Techniques

2021 IEEE International Conference on Consumer Electronics (ICCE), 2021
Logic 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 the Limitations of Logic Locking the Approximate Circuits

2022 Asian Hardware Oriented Security and Trust Symposium (AsianHOST), 2022
Approximate 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
