Issue Date: | 28-Jul-2020 | Citation: | SACHIN TANEJA, ALIOTO,MASSIMO BRUNO (2020-07-28). Fully-Synthesizable All-Digital Unified Dynamic Entropy Generation, Extraction and Utilization in a Cryptographic Core for Constrained Secure Systems. IEEE ASSCC 2020. ScholarBank@NUS Repository. | Abstract: | This work introduces a novel class of fully-synthesizable all-digital True Random Number Generators (TRNGs) using the same private-key cryptographic core for raw dynamic entropy generation, its extraction via post-processing, and its utilization as crypto-key for constrained secure systems. Endogenous random bit generation is achieved via clock pulsewidth overstretching in the digital implementation of private-key cryptographic algorithms using pulsed-latch pipelines, leveraging inherent Shannon confusion and diffusion. Demonstration on a 40-nm testchip based on a SIMON cryptographic core shows 64-bit key encryption down to 0.25 pJ/bit at 0.45 V, random number generation with cryptographic-grade entropy at 2.5 pJ/bit across manufacturing lots, dice, voltages and temperature corners. The overall area is kept well below the 1E6 F2 area wall (F = minimum feature size). | Source Title: | IEEE ASSCC 2020 | URI: | https://scholarbank.nus.edu.sg/handle/10635/172972 |
