I would prefer not to wait. Unlike a new primitive whose strength can
only be known through attempts at cryptanalysis, Adiantum is a
construction based on
well-understood and trusted primitives; it is secure if the proof
accompanying it is correct. Given that (outside competitions or
standardization efforts) no-one ever issues public statements that
they think algorithms or proofs are good, what I'm expecting from
academia is silence :) The most we could hope for would be getting the
paper accepted at a conference, and we're pursuing that but there's a
good chance that won't happen simply because it's not very novel. It
basically takes existing ideas and applies them using a stream cipher
instead of a block cipher, and a faster hashing mode; it's also a
small update from HPolyC. I've had some private feedback that the
proof seems correct, and that's all I'm expecting to get.
