A routerupdate method for tor anonymous communication system

Among all the anonymous communication systems, Onion Routing is most widely used. Tor affords users with anonymous service in communication. It can be used in running anonymous web browsing and announcement, real-time communications, IRC, SSH and other TCP applications. After analyzing the source code of the Tor system, this paper introduced the network layout, working flow, the RouterUpdate method of establishing a virtual circuit and data sending or receiving in Tor system. The method helps Tor client using the relay nodes which have been stored to connect the internet of Tor without connecting the list server. Then the paper introduced a method to help the Tor client using all the applications whether or not using the SOCKS. © 2013 Springer Science+Business Media New York.
