Optimally Secure Tweakable Block Ciphers with a Large Tweak from n-bit Block Ciphers
We consider the design of a tweakable block cipher from a block cipher whose inputs and outputs are of size n bits. The main goal is to achieve 2n security with a large tweak (i.e., more than n bits). Previously, Mennink at FSE’15 and Wang et al. at Asiacrypt’16 proposed constructions that can achi...
