Secure peer-to-peer networking: the JXTA example

The JXTA framework's key benefit is its ability to provide security via well-understood, trusted approaches. Likewise, JXTA's transport protocol independence lets applications avoid the security breaches imposed by gateways or other network infrastructure. Project JXTA has now completed J2SE and J2ME MIDP implementations.The latter is for small-footprint devices like mobile phones. A C implementation is nearly completed. These three are edge-to-edge interoperable and thus will provide JXTA P2P functionality across the device space. At JavaOne 2002, held in San Francisco during March, developers demonstrated group instant messaging among mobile phones, laptops, and desktop systems with firewall traversal, using the JXTA protocols.An open-source framework, JXTA can accommodate centralized and decentralized certificate authorities for P2P networking.
