Natural Language Processing for Hardware Security: Case of Hardware Trojan Detection in FPGAs

Cryptography
Field-programmable gate arrays (FPGAs) offer the inherent ability to reconfigure at runtime, making them ideal for applications such as data centers, cloud computing, and edge computing. This reconfiguration, often achieved through remote access, enables

FPGA-Based Chaotic Oscillator Designs and Performance Analysis

Chaos and Fractals
Chaotic systems are highly sensitive to initial conditions, where even minute changes can result in vastly different outcomes. The non-linear nature of chaotic systems prevents them from reaching a stable state, instead exhibiting continuous change ...
