  Cryptoprimitives rely on thorough theoretical background, but often lack
basic usability features making them prone to unintentional misuse by
developers. We argue that this is true even for the state-of-the-art designs.
Analyzing 52 candidates of the current CAESAR competition has shown none of
them have an avalanche effect in authentication tag strong enough to work
properly when partially misconfigured. Although not directly decreasing their
security profile, this hints at their security usability being less than
perfect. Paper details available at crcs.cz/papers/memics2016
