Hybrid Shielding: Amplifying the Power of Camouflaging and Logic Encryption

IEEE Access, 2023
In the semiconductor industry, protecting Integrated Circuits (IC) throughout the IC supply chain has become a major concern. In-depth research has been done on logic encryption, split manufacturing, and layout camouflaging to safeguard ICs against ...

Boolean Computation Using Self-Sustaining Nonlinear Oscillators

, 2015
Self-sustaining nonlinear oscillators of practically any type can function as latches and registers if Boolean logic states are represented physically as the phase of oscillatory signals.

Locking-Enabled Security Analysis of Cryptographic Circuits

Cryptography
Hardware implementations of cryptographic primitives require protection against physical attacks and supply chain threats. This raises the question of secure composability of different attack countermeasures, i.e., whether protecting a circuit against ...

Logic Locking: Exploration of a new key-gate based on tristate logic

Latin American Test Symposium
As a consequence of the tremendous rapid pace of semiconductor technology evolution over the last decades, most semiconductor companies have become fabless and outsource the manufacturing step of their designs to offshore foundries.

ProbLock: Probability-based Logic Locking

, 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. Only the correct key can unlock the functionality of that circuit otherwise the system produces the wrong output ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

Advanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Synchronization of Coupled Boolean Phase Oscillators

, 2014
We design, characterize, and couple Boolean phase oscillators that include state-dependent feedback delay. The state-dependent delay allows us to realize an adjustable coupling strength, even though only Boolean signals are exchanged.
