PTPerf: On the Performance Evaluation of Tor Pluggable Transports
Zeya Umayya, Dhruv Malik, Devashish Gosain, Piyush Kumar Sharma · 2023
Tor, one of the most popular censorship circumvention systems, faces regular blocking attempts by censors. Thus, to facilitate access, it relies on "pluggable transports" (PTs) that disguise Tor's traffic and make it hard for the adversary to block Tor. However, these are not yet well studied and compared for the performance they provide to the users. Thus, we conduct a first comparative performance evaluation of a total of 12 PTs-the ones currently supported by the Tor project and those that can be integrated in the future.
