SHA-1 collisions now 2^52

[Dustin D. Trammell]

"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."
