Mona Wang is presenting her work on countering network surveillance.
Network-level adversaries have been developing increasingly sophisticated techniques to perform surveillance and exert control over user traffic. We present a novel Connection Migration Powered Splitting (CoMPS) framework to construct multiple new defenses against various traffic analysis attacks. CoMPS limits the amount of information a particular adversary can observe on the network by performing traffic splitting within individual sessions. CoMPS is the first to fully support mid-session traffic splitting across heterogeneous network paths and protocols, without the need for deploying additional network infrastructure. CoMPS is not only readily deployable with any protocol supporting connection migration (e.g., QUIC, WireGuard, and Mosh), but incurs very little overhead.
