The state of the art on resisting end-to-end statistical attacks by an
attacker who can watch both ends of a low-latency anonymity channel,
is IMO Shmatikov and Wang's "Adaptive Padding":
The paper mentiones earlier research in the area, which is also pretty
important. IMO none of it is useful enough yet to merit inclusion in
Tor, but it might be on the right path.
For a paper with interesting implications for path selection stuff, I
like Steven Murdoch's
It refers to some earlier papers that are also pretty important.
You might also check out other related papers on anonbib; there's some
good research been happening in the last few years. IMO, new defenses
are generally more interesting than new attacks, since the attacks are
already so good that new, equally good attacks aren't very impressive.
hope this helps,
