Enhancing Provable Security and Efficiency of Permutation-based DRBGs
Abstract
We revisit the security analysis of the permutation-based deterministic random bit generator~(DRBG) discussed by Coretti et al. at CRYPTO 2019. Specifically, we prove that their construction, based on the sponge construction, and hence called Sponge-DRBG in this paper, is secure up to
