DNSCatProxy: A Pluggable Transport based on DNS Tunneling Irvin Zhan Abstract

Relays within the Tor network are unable to link a connection’s source and destination, nor are the servers that the Tor users connect to able to figure out the IP address of the Tor user. This is because the Tor protocol uses a layered system ...
