We describe highly efficient constructions, XE and XEX, that turn a blockcipher E: K x{0, 1}n → {0, 1}n into a tweakable blockcipher Ẽ: K x T x {0, 1}n → {0, 1}n having tweak space T = {0,1}n II where II is a set of tuples of integers such as II = [1.. 2n/2] X [0.. 10]. When tweak T is obtained from...
