I'm not aware of a more recent cryptanalysis of the revised work, the assumption he's making now is that if there are no further optimizations (knock on wood) then the properties he's going for will hold. https://github.com/tromp/cuckoo/raw/master/cuckoo.pdf (Breaking the current construction will apparently earn you some beer money though!) > Cohen's idea is collision search; it is known to be performed Yep, which was also what I pointed out to him too... He's gone of in a fairly different direction since then.
