Jxtanonym: An Anonymity Layer For Jxta Services Messaging

With the evolution of the P2P research field, new problems, such as those related with information security, have arisen. It is important to provide security mechanisms to P2P systems, since it has already become one of the key issues when evaluating them. However, even though many P2P systems have been adapted to provide a security baseline to their underlying applications, more advanced capabilities are becoming necessary. Specifically, privacy preservation and anonymity are deemed essential to make the information society sustainable. Unfortunately, sometimes, it may be difficult to attain anonymity unless it is included into the system's initial design. The JXTA open protocols specification is a good example of this kind of scenario. This work studies how to provide anonymity to JXTA's architecture in a feasible manner and proposes an extension which allows deployed services to process two-way messaging without disclosing the endpoints' identities to third parties.
