Decided that as I get mentioned in other people's diaries, I probably should write some of my own. I'm thinking a lot about traffic analysis lately; how to quantify it, how to drive it forward as a scientific field. Or maybe I should back up and say that traffic analysis is tea-leaf reading, where you examine all of the stuff about a message that isn't encrypted, and learn about social and organizational networks. The state of the art is totally dominated by the NSA, and they're not talking.
