On the Interplay of Modern Traffic Analysis and Internet Censorship & Circumvention Techniques
In this talk, I will review the current state of real-world Internet censorship and some tools that network users employ to circumvent censorship. Then, I'll take a prospective view about how censors might incorporate modern ML-based traffic analysis techniques to block users, motivating the need for stronger circumvention tools. Finally, I'll discuss our new internet censorship evasion technique called Unidentified Protocol Generation (published at USENIX Security 2025, which is able to evade detection by state-of-the-art traffic analysis.
