-Princeton paper:
-\begin{itemize}
-\item Recognize that they can perform activity detection by observing changes in traffic volume over time
-\item However, they cannot distinguish on/off from each other
-\item Proposed traffic shaping does not prevent activity inference from the observation of packet lengths in specific sequences (assuming no VPN)
-\end{itemize}
-Cisco paper:
-\begin{itemize}
-\item Also uses DNS for contextual information
-\item Refers to previous work that considers packet lengths and sequences of packets (and uses this themselves)
-\end{itemize}
