This is really amazing stuff. I just read their PDF and they make a
suggestion how a new kind of "quick check" could like like: adding the
hash of the symmetric key... I'm not a cryptologist, but this sounds
absolutely crazy, this would mean in the future the security of
symmetric encryption relies not only on the cipher, but on a hash
algorithm... regarding the recent discussions and rumours about hash
algorithms in general, is this really safer!?
Are there several different ideas what the new "quick check" could look
like or is there even already a consesus what it could look like?
