STRIBOB / WHIRLBOB Security Analysis Addendum

Markku-Juhani O. Saarinen

Abstract

This memo collects references to published cryptanalytic results which are directly relevant to the security evaluation of CAESAR first round algorithm STRIBOB and its second round tweaked variant, WHIRLBOB. During the first year after initial publication of STRIBOB and WHIRLBOB, no cryptanalytic breaks or other serious issues have emerged. The main difference in the security between the two variants is that WHIRLBOB allows easier creation of constant-time software implementations resistant to cache timing attacks.
