traffic analysis (which is an art, not a science, remember).
Are you sure TA is still an art? The NSA has (presumably) spent thousands of man years on the problem. Hal, Wei Dai and others have done some very good work. While I've only skimmed the surface of it, its clear that clever statistical work comprises a lot of TA.
Adam is correct, as least if you believe Bamford. _The Puzzle Palace_ lists some of the courses in the NSA's 3-year Traffic Analysis Intern Program, along with some entertaining questions from the Agency's aptitude test designed to ferret out potential traffic analysts. IMO, far more science than art is involved.
