Description

The JonDonym documentation states, "[...] TCP timestamps can be used for tracking [...]" and "The JonDonym mixes automatically replace your potentially insecure TCP packets by their own.".

Tor should probable do the same or state somewhere why they believe why it's not necessary.


Sorry, if this is a duplicate or elsewhere documented. Search term site:torproject.org TCP timestamp or similar didn't bring results.

If I understand their web page correctly, Tor does this automatically just like the Jondonym mixes do. It's a property you get for free by terminating the underlying traffic flows at each hop rather than packaging up IP packets and sending them across the network.

See e.g. https://trac.torproject.org/projects/tor/wiki/doc/TorFAQ#DoesTorresistremotephysicaldevicefingerprinting

Though, ugh, the faq entries around that on the torfaq have been overrun by idiots. I wonder if I should transfer that particular faq entry over to the 'real' faq.

arma: I think that could be a clever thing to do

How was this fixed? @Sebastian

comment:6 Changed 5 years ago by Sebastian

I marked it fixed because we moved the faq entry.

(Please reopen with what we still need to do if you feel this wasn't adequate)
