Towards a Formal Treatment of Logic Locking
Iacr Transactions on Cryptographic Hardware and Embedded Systems, 2022 Logic locking aims to protect the intellectual property of a circuit from a fabricator by modifying the original logic of the circuit into a new “locked” circuit such that an entity without the key should not be able to learn anything about the original circuit.

Quantum Logic Locking for Security
J, 2022 Having access to a unique quantum circuit that one wants to protect against use by others is a very likely scenario. However currently users rely on classical computer security schemes, which have known shortcomings. In this chapter we introduce a novel protection scheme along with a survey of other known methods to protect quantum information.

Functional Analysis Attacks on Logic Locking [PDF]
IEEE Transactions on Information Forensics and Security, 2019 Logic locking refers to a set of techniques that can protect integrated circuits (ICs) from counterfeiting, piracy and malicious functionality changes by an untrusted foundry. It achieves these goals by introducing new inputs, called key inputs, and additional logic to an IC such that the circuit produces the correct output only when the key inputs are

Modeling techniques for logic locking [PDF]
Proceedings of the 39th International Conference on Computer-Aided Design, 2020 Logic locking is a method to prevent intellectual property (IP) piracy. However, under a reasonable attack model, SAT-based methods have proven to be powerful in obtaining the secret key. In response, many locking techniques have been developed to specifically resist this form of attack.

Latch-Based Logic Locking [PDF]
2020 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), 2020 Globalization of IC manufacturing has led to increased security concerns, notably IP theft. Several logic locking techniques have been developed for protecting designs, but they typically display very large overhead, and are generally susceptible to deciphering attacks.

Breaking CAS-Lock and Its Variants by Exploiting Structural Traces
Transactions on Cryptographic Hardware and Embedded Systems, 2021 Logic locking is a prominent solution to protect against design intellectual property theft. However, there has been a decade-long cat-and-mouse game between defenses and attacks. A turning point in logic locking was the development of miterbased Boolean

A Security Analysis of Circuit Clock Obfuscation
Cryptography, 2022 Key-based circuit obfuscation or logic-locking is a technique that can be used to hide the full design of an integrated circuit from an untrusted foundry or end-user. The technique is based on creating ambiguity in the original circuit by inserting “key”

A Novel Probability-Based Logic-Locking Technique: ProbLock
Sensors, 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.

A Comparative Study of Different Control Methods for Anti-Lock Braking System (ABS) [PDF]
SVU-International Journal of Engineering Sciences and Applications, 2021 The anti-lock braking system (ABS) can detect the wheels locking and also modulate the brake pressure in order to prevent the wheel from locking. The main objectives of controlling the ABS is giving the controlled required torque to obtain the optimal ...

Noise‐based logic locking scheme against signal probability skew analysis
IET Computers & Digital Techniques, 2021 Due to integrated circuit (IC) production chain globalisation, several new threats such as hardware trojans, counterfeiting and overproduction are threatening the IC industry. So logic locking is deployed to hinder these security threats.
