A few weeks ago, we had a brief exchange on this list about traffic
analysis, specifically the collection and analysis of IP packet headers. I
wanted to write a draft describing the issue and proposing solutions, but
the day job interfered and I was delayed. With that, I missed the cutoff
date by many days. But the good news is that I finally wrote a first cut of
this draft, and put it on a personal web server:
Passive Traffic Analysis Threats and Defense
draft-huitema-perpass-analthreat-00.txt
Abstract
Traffic analysis is used by various entities to derive "meta data"
about Internet communications, such as who communicates with whom or
what, and when. We analyze how meta-data can be extracted by
monitoring IP headers, DNS traffic, and clear-text headers of
commonly used protocols. We then propose a series of actions that
would make traffic analysis more difficult.

I am sure that this draft could be much improved with feedback from this
list!
