Abstract

I present a traffic analysis based vulnerability in SafeWeb, an encrypting web proxy. This vulnerability allows someone monitoring the traffic of a SafeWeb user to determine if the user is visiting certain websites. I also describe a successful implementation of the attack. Finally, I discuss methods for improving the attack and for defending against the attack.
