Truly Stripping Functionality for Logic Locking: A Fault-Based Perspective

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2020
Logic locking is a holistic solution to counter manufacturing threats, such as intellectual property (IP) piracy and overbuilding at the hardware level. However, years of research has exposed various flaws in locking, including a Boolean satisfiability (SAT)-based attack. Consequently, several SAT-resilient locking techniques, such as SARLock, Anti-SAT,

Zzyzx: Scalable fault tolerance through Byzantine locking

2010 IEEE/IFIP International Conference on Dependable Systems & Networks (DSN), 2010
Zzyzx is a Byzantine fault-tolerant replicated state machine protocol that outperforms prior approaches and provides near-linear throughput scaling. Using a new technique called Byzantine Locking, Zzyzx allows a client to extract state from an underlying replicated state machine and access it via a second protocol specialized for use by a single client.

The Effects of Locked-in Pressure on the Mechanics of Faulting

Seismological Research Letters, 2008
Static friction and dynamic friction between two surfaces are generally proportional to the normal force between the surfaces. Pressure in the Earth is approximately equal to the lithostatic overburden. It follows that the failure strength of a fault and its resistance to sliding should increase with depth below the surface. Or should it?

Lock-in Amplifier Applications for Fault Isolation

International Symposium for Testing and Failure Analysis
Abstract This paper describes how lock-in amplifiers and boxcar averaging can overcome limitations in conventional fault isolation techniques for microelectronic testing. Our approach achieves superior results compared to traditional spectrum analyzer methods through three key applications.

Fault tolerant gaits of legged robots for locked joint failures

SMC 2000 Conference Proceedings. 2000 IEEE International Conference on Systems, Man and Cybernetics. 'Cybernetics Evolving to Systems, Humans, Organizations, and their Complex Interactions' (Cat. No.00CH37166), 2002
In this paper, fault detection and tolerance in static walking of legged robots are addressed. A kind of fault events, locked joint failure, is defined and its properties are investigated in the frame of gait study and robot kinematics. For the purpose of tolerating a locked joint failure, an algorithm of fault tolerant gaits for a quadruped robot is ...

Fault-based Built-in Self-test and Evaluation of Phase Locked Loops

ACM Transactions on Design Automation of Electronic Systems, 2021
With the increasing pressure to obtain near-zero defect rates for the automotive industry, there is a need to explore built-in self-test and other non-traditional test techniques for embedded mixed-signal components, such as PLLs, DC-DC converters, and data converters.

An FDI approach for aircraft actuator lock-in-place fault

2007 IEEE International Conference on Control and Automation, 2007
In this paper, an adaptive observer approach is developed to detect and isolate aircraft actuator faults. Particularly, the fault of actuator locked in place is considered. In a multiple-model scheme, a bank of parallel observers are constructed, each of which is based on a model that describes the system in the presence of a particular actuator fault.

Fault Localization and Functional Testing of ICs by Lock-in Thermography

International Symposium for Testing and Failure Analysis, 2002
Abstract In this paper new thermographic techniques with significant improved temperature and/or spatial resolution are presented and compared with existing techniques. In infrared (IR) lock-in thermography heat sources in an electronic device are periodically activated electrically, and the surface is imaged by a free-running IR camera.

Hardening of Smart Electronic Lock Software against Random and Deliberate Faults

2020 23rd Euromicro Conference on Digital System Design (DSD), 2020
In this research paper, analysis of smart electronic lock behavior during presence of faults in its controller is examined. A typical smart electronic lock is composed of a controller unit, usually implemented in a processor, and the mechanical part, which may be for example a stepper motor.
