In this work, we examine the potential of Physical Unclonable Functions (PUFs) that have been implemented on NAND Flash memories using programming disturbances to act as sustainable primitives for the purposes of lightweight cryptography. In particular, we investigate the ability of such PUFs to tolerate temperature and voltage variations, and examine the current shortcomings of existing NAND-Flash-memory PUFs that are based on programming disturbances as well as how these could potentially be addressed in order to provide more robust and more sustainable security solutions.

This work was accepted for and presented at the Workshop on Sustainability in Security, Security for Sustainability, which took place on 18 March 2022 and was co-located with the 25th Design, Automation and Test in Europe Conference & Exhibition (DATE 2022).
