Large scale malicious activities continue to take place on the Internet. Safeguarding vulnerable computers and servers is therefore important. Recently, systems have been proposed to protect network addresses of computers from malicious adversaries on the Internet. Some of these systems focus specifically on providing client-side anonymity. However, as the Internet bandwidth for average users continues to increase, individuals are increasingly capable of carrying out complicated tasks as servers. It is in the interest of the individuals to gain server anonymity in which the network address of the machine remains protected from malicious activities. In this paper, we present a Scalable Anonymous Server Overlay Network (SASON) that aims at protecting network addresses of all participating servers. SASON also provides reliable server discovery and routing through the use of server pseudonyms and distributed hashtables.
