Does the \DESX trick" really work to improve the strength of DES against exhaustive key search? This paper will give a strong positive result showing that.
Jul 23, 2015 · This construction was first suggested by Rivest as a computationally cheap way to protect DES against exhaustive key-search attacks.

Abstract. The block cipher DESX is defined by DESXk.k1.k2(x) = k2 ⊕ DESk. (k1 ⊕ x), where ⊕ denotes bitwise exclusive-or. This construction was first ...

This paper proves, in a formal model, that the DESX construction is sound. We show that, when F is an idealized block cipher, FXk.k1.k2(x)= K2 ⊕ Fk(k1 ⊕ x) is ...
