Preventing SSL Traffic Analysis with Realistic Cover Traffic (extended abstract)

In this paper, we introduce the basic design and eval- uation of a cover traffic tunneling system called Traf- ficMimic. We utilize methods for generating realistic cover traffic, borrowing from prior work on traffic gen- eration from the simulation and modeling research com- munity (10). Using several protocol classification and anomaly detection attacks, we show that TrafficMimic is able to reproduce cover traffic reliably and securely. Lastly, we show that realistic cover traffic provides com- parable performance to constant-rate techniques, and in some cases can be very efficient. 2 TrafficMimic Design
