Real-time Steganography with RTP

August 9, 2007

Last weekend I gave my presentation at DEFCON 15 entitled Real-time Steganography with RTP. At the same time, I released my reference implementation for the research which is called SteganRTP.

First, let me say that I hate computers. I hate them, hate them, hate them. Upon booting up my laptop in the speaker green room prior to my talk it decided to have all kinds of problems with my live demo setup. The audio was choppy, the endpoints didn’t want to sync up, basically mass chaos all contained within my laptop. Luckily I had gotten to the green room fairly early so after some quick debugging and a reboot everything was operating fine. It was a close call though, as the very minute I got it all back to normal it was time to walk down to the room I was scheduled to speak in.

My talk was essentially about a research project I’ve been working on for the past couple months in what little spare time I’ve had at home involving hiding a data communications protocol inside a VoIP call’s audio. My talk went well, although I did rush through it a bit hoping to end close to my allotted 50 minutes but I actually ended up finishing about 10 minutes early. Since I finished early I went ahead and took questions there in addition to later in the Q&A room for my track. I had some fairly good questions and one stupid question from intropy & co. at the back of the room (: I then went over to my Q&A room where this one guy proceeded to ask me questions for almost the entire next hour.

Anyhow, my presentation went really well, and you can check out the slides and the tool at the links above.
