DNS over HTTPS (DoH) obviates many but not all of the risks, and its transport protocol (i.e. HTTPS) raises concerns of privacy due to (e.g.) 'cookies.' The Tor Network exists to provide TCP circuits with some freedom from tracking, surveillance, and blocking. Thus: In combination with Tor, DoH, and the principle of "Don't Do That, Then" (DDTT) to mitigate request fingerprinting, I describe DNS over HTTPS over Tor (DoHoT).
We investigate whether DoH traffic is distinguishable from encrypted Web traffic. To this end, we train a machine learning model to classify HTTPS traffic as either Web or DoH. With our DoH identification model in place, we show that an authoritarian ISP can identify ≈97.4% of the DoH packets correctly while only misclassifying 1 in 10,000 Web packets.
