Walkie-Talkie...
summary
Modifies the browser and Tor guard to enforce half-duplex page loading, grouping packets into moldable bursts and merging two pages’ burst sequences so they are indistinguishable; tested on ~10,000 pages and against state‑of‑the‑art classifiers, it yields 31% bandwidth overhead and 34% time overhead while capping attacker success at about 50% max attacker accuracy when merging two pages (lower with more merges), and defeats the known WF attacks in the evaluation.
