Abstract: We design, implement, and evaluate CovertCast, a censorship circumvention system that broadcasts the content of popular websites in real-time, encrypted video streams on common live-streaming services such as YouTube. CovertCast does not require any modifications to the streaming service and employs the same protocols, servers, and streaming software as any other user of the service. Therefore, CovertCast cannot be distinguished from other live streams by IP address filtering or protocol fingerprinting, raising the bar for censors.
