"Until now, the best complete differential path (to our knowledge)
has complexity 2^63
The new path presented has complexity 2^52 - a significant reduction.
Practical collisions are within resources of a well funded organisation.
We are continuing our search for differential paths where the
boomerang attack can be used with maximum effect.
Paper will appear on eprint soon."
