This post is meant to update the list of open Tor research problems, to bring focus to specific areas of research that the Tor Project thinks are necessary/useful in our efforts to upgrade and improve the Tor network and associated components and software. It is organized by topic area: network performance, network security, censorship circumvention, and application research. Each topic area provides information about current and desired work and ideas. We conclude with information about doing ethical and useful research on Tor and with suggestions on how to best ensure that this work is useful and easy for us to adopt.
