FPGA Implementation of Metastability-Based True Random Number Generator
True random number generators (TRNGs) are important as a basis for computer security. Though there are some TRNGs composed of analog circuit, the use of digital circuits is desired for the application of TRNGs to logic LSIs. Some of the digital TRNGs utilize jitter in freerunning ring oscillators as a source of entropy, which consume large power. Another type of TRNG exploits the metastability ...

We present novel architecture for True Random Number Generator based on Transition Effect Ring Oscillators. The TRNG consists of 16 transition effect oscillators and also malfunction detector. The malfunction detector can evaluate each TRNG bit right after it was generated. The evaluation utilizes described TRNG mathematical model. Our designed True Random Number Generator is implemented in Act...
متن کاملTrue random number generator based on metastability of RS latch 市川周一 ∗
多くのセキュリティ技術は,その安全性の根拠を乱数 に依存している.そのため,ハードウェアによる真性乱 数の生成は,実用上極めて重要である. 真性乱数生成回路 (TRNG; true random number generator)については,これまでも多くの研究が行われてきた. 例えば熱雑音等の物理現象に基づいた TRNGが実用化 されているが,これらはアナログ回路で実装されており, デジタル回路との混在は簡単でない.デジタル回路だけ で TRNGを構成することができれば,論理回路と容易 に接続でき,論理 LSI上に集積することも可能になる. 本研究では,RSラッチのメタスタビリティを利用し た TRNGを設計・実装し,その評価結果を報告する.こ の回路は同期式デジタル回路で構成されているため,基 本的に全ての論理 LSI上で実現可能である.本研究では 実装評価に FPGAを使用した...
متن کاملFPGA-Based True Random Number Generation Using Circuit Metastability with Adaptive Feedback Control
The paper presents a novel and efficient method to generate true random numbers on FPGAs by inducing metastability in bi-stable circuit elements, e.g. flip-flops. Metastability is achieved by using precise programmable delay lines (PDL) that accurately equalize the signal arrival times to flip-flops. The PDLs are capable of adjusting signal propagation delays with resolutions higher than fracti...

In this report, we introduce the background of random number generator(RNG) and true random number generate based on ring oscillator(RO). We present the design of improved 3-edge Ring Oscillator and its layout. Based on Cadence spectre transient simulation tools, the output is recorded and then processed in Matlab,where the randomness tests are conducted. Keywords—TRNG; Simulation; Cadence;VLSI...
