A Closer Look at the Delay-Chain based TRNG [PDF]

2018 IEEE International Symposium on Circuits and Systems (ISCAS), 2018
This paper presents a refined stochastic model of the delay-chain based true random number generator (DC-TRNG) and its application. DC-TRNG is a true random number generator for FPGAs that utilizes time-to-digital conversion (TDC) to accurately determine the position of the ring-oscillator jittery signal edge.

Voltage‐Reconfigurable Magneto‐Ionic Nanolayers in Dot Arrays for Probabilistic, Materials‐Engineered Security Primitives

Advanced Science, EarlyView.
A magneto‐ionic security‐by‐materials‐design strategy exploits voltage‐driven N3– migration in selectively contacted FeCoN dots, creating reconfigurable sub‐15 nm ferromagnetic sublayers with deterministic and/or probabilistic (single‐domain↔vortex) states, voltage‐tunable probabilities and fully stochastic orientation/chirality.

On the Characterization of Phase Noise for the Robust and Resilient PLL-TRNG Design

Transactions on Cryptographic Hardware and Embedded Systems
A true random number generator (TRNG) is a critical component in ensuring the security of cryptographic systems. Among TRNG implementations, the phase-locked loop-based TRNG (PLL-TRNG) is a widely adopted solution for FPGA platforms due to the ...

RRAM Variability Harvesting for CIM‐Integrated TRNG

Advanced Electronic Materials, EarlyView.
This work demonstrates a compute‐in‐memory‐compatible true random number generator that harvests intrinsic cycle‐to‐cycle variability from a 1T1R RRAM array. Parallel entropy extraction enables high‐throughput bit generation without dedicated circuits. This approach achieves NIST‐compliant randomness and low per‐bit energy, offering a scalable hardware

DH-TRNG: A Dynamic Hybrid TRNG with Ultra-High Throughput and Area-Energy Efficiency

Proceedings of the 61st ACM/IEEE Design Automation Conference
As a vital security primitive, the true random number generator (TRNG) is a mandatory component to build roots of trust for any encryption system. However, existing TRNGs suffer from bottlenecks of low throughput and high area-energy consumption. In this work, we propose DH-TRNG, a dynamic hybrid TRNG circuitry architecture with ultra-high throughput ...

Application of a MEMS-Based TRNG in a Chaotic Stream Cipher [PDF]

Sensors, 2017
In this work, we used a sensor-based True Random Number Generator in order to generate keys for a stream cipher based on a recently published hybrid algorithm mixing Skew Tent Map and a Linear Feedback Shift Register. The stream cipher was implemented and tested in a Field Programmable Gate Array (FPGA) and was able to generate 8-bit width data streams

Compact Modeling of Volatile‐Switching Electrochemical Metallization Memory Cells by Means of the Electromotive Force

Advanced Intelligent Systems, EarlyView.
A volatile‐switching compact model of electrochemical metallization memory cells for neuromorphic architecture is developed and validated by reliable reproduction of device characterization measurements: I−V sweeps, SET kinetics, relaxation dynamics.

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

Nordic Journal of Botany, EarlyView.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

Restored wetlands: interplay between environmental variables, aboveground and belowground plant traits, and carbon cycling

New Phytologist, EarlyView.
Assessing relationships between environmental conditions, aboveground and belowground plant traits, and carbon cycling in restored wetlands (grazed and ungrazed), compared to a baseline in near‐natural wetlands in Denmark, revealed that ecosystem functions can be restored, even in cases where plant biodiversity has not recovered.

RNA‐Guided Engineering of the Chloroplast Genome Enabled by Plastid‐Expressed Guide RNAs

Plant Biotechnology Journal, EarlyView.
ABSTRACT Our goal is to develop RNA‐guided engineering of the chloroplast genome using the CRISPR/Cas9 system. We designed chloroplast minigenes to obtain properly sized single guide RNAs (sgRNAs) in tobacco chloroplasts. The sgRNA 5′ end is defined by transcription from an rRNA operon promoter, and its 3′ end by processing a downstream tRNA (trnG) or ...
