ePrint Report: Lightweight Leakage-Resilient PRNG from TBCs using Superposition

Mustafa Khairallah, Srinivasan Yadhunathan, Shivam Bhasin

In this paper, we propose a leakage-resilient pseudo-random number generator (PRNG) design that leverages the rekeying techniques of the PSV-Enc encryption scheme and the superposition property of the Superposition-Tweak-Key (STK) framework. The random seed of the PRNG is divided into two parts; one part is used as an ephemeral key that changes every two calls to a tweakable block cipher (TBC), and the other part …
