Technische Universiteit Eindhoven is organizing a one-day workshop in Utrecht, the Netherlands, on Friday 17 July 2015, to publicly identify critical ongoing challenges in authenticated encryption, looking beyond the CAESAR competition. This is a workshop in the classic sense, featuring intense interactive discussions among serious people, strictly limiting the amount of time used for lectures, and keeping laptops closed.
