Constructions of Beyond-Birthday Secure PRFs from Random Permutations, Revisited
In CRYPTO 2019, Chen et al. showed how to construct pseudorandom functions (PRFs) from random permutations (RPs), and they gave one beyond-birthday secure construction from sum of Even-Mansour, namely [Formula: see text] in the single-key setting. In this paper, we improve their work by proving the...
