Comment (by zmer): INTRO cells used to have a timestamp that could be used to discard old ones being replayed. All things considered, the reasons given for removing it didn't make good sense. Arguably it should be brought back. And perhaps in future clients could be made to keep their own accurate time, independent of what the host clock is set to. There would be a number of benefits. But that is another ticket. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/26294#comment:37> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
