On Large Tweaks in Tweakable Even-Mansour with Linear Tweak and Key Mixing
IACR Transactions on Symmetric Cryptology, 2023 In this paper, we provide the first analysis of the Iterated Tweakable Even-Mansour cipher with linear tweak and key (or tweakey) mixing, henceforth referred as TEML, for an arbitrary tweak(ey) size kn for all k ≥ 1, and arbitrary number of rounds r ≥ 2.
