New description:
As a defense against Website Traffic Fingerprinting, we should implement a
tunable cover traffic defense that we could set from the consensus with a
value dependent upon available Guard bandwidth relative to Exit capacity.
My favorite from the research literature is
http://freehaven.net/anonbib/cache/ShWa-Timing06.pdf, because it appears
to be tunable in this fashion.
The "BUFLO" variant proposed by this paper is better specified, but it's
not clear it actually performs better for a given overhead quantity:
http://www.cs.sunysb.edu/~xcai/fp.pdf
This is likely a research task. People who attempt it should also read
http://ksubrick.ist.psu.edu/viewdoc/summary?doi=10.1.1.1.8982 (Direct
link, since citeseer is often down:
http://www.raid-symposium.org/raid99/PAPERS/Axelsson.pdf)
