Design and Analysis of Secure and Anonymous Communication System Based on Tor
Yiqi Dai · Journal of Beijing Electronic Science and Technology Institute · 2009
0 With the emergence of traffic analysis and other such attacks,anonymous system is applied more and more widely,which withstands these attacks well.It not only encrypts the communication data but also hides clients from the receiving party and the network to improve clients' privacy.This paper proposes a new secure and anonymous communication framework based on Tor,which is now a popular anonymous overlay network.In the aspect of system implementation,it deploys secure directory servers and secure relays.Then it designs and implements the communication module between local host proxy and secure relay as well as the communication between secure relay and secure directory server.Furthermore,it introduces into the concept of secret sharing and achieves a preliminary execution of multi-path routing to find a possible way to improve security and performance.
