The iterated Even-Mansour construction defines a block cipher from a tuple of public n-bit permutations $P_1,\\ldots ,P_r$ by alternatively xoring some n-bit round key $k_i$, $i=0,\\ldots ,r$, and applying permutation $P_i$ to the state. The tweakable Even-Mansour construction generalizes the conventional Even-Mansour construction...More
