Does tor mask packet sizes?

Question

Computer networks

I need to find out if tor reliably masks only ip or the size of packets too?
Knowing the size of the packets sent by the user to the destination server and the size of the packets received by the user from the destination server, is it possible to calculate a specific user even if he uses tor?

Answer 1

No, it doesn't disguise.
On tor, a packet size attack and a timing attack are possible.
