Comment (by atagar):

 > This is the node which knows IP of Tor user. If guard is known it is
 very simple to deanonymize tor user.

 This is incorrect. Eavesdropping on a guard simply tells you that someone
 is using tor. Not where they're going. Deanonymization, say via a
 correlation attack, requires monitoring both your entry *and* exit
 traffic.

 The strength of tor is this distribution of information. It's easy (albeit
 malicious and in many places illegal) to snoop on who uses tor by running
 a guard. It's also easy to figure out what tor is being used for by
 snooping on an exit. What tor makes difficult is **deanonymizing** you
 which requires both at the same time, which thanks to the size of the tor
 network is quite difficult.
