novel type of P2P VPN

This paper has described a novel type of P2P VPN that enables the creation of secure, private networks regardless of the peer locations, network access type, or operating system. Unlike the current VPN generation, N2N is fully decentralised and uses supernodes only at start-up or whenever peers are behind symmetric NATs that prevent direct peer communication. Existing applications do not need to be changed in any way to exploit N2N. The ability to tunnel N2N traffic over protocols such as HTTP and DNS makes it a very useful technology for allowing users to overcome restrictions in many networks. N2N users can be partitioned into networks and have a permanent, unique N2N IP address regardless of the current address of the device running N2N. This makes N2N suitable for creating overlay networks of users sharing homogeneous information. Finally, traffic encryption at the edge and not by any controlling entity, enables users to securely exchange sensitive information with much less risk of being intercepted or observed by unwanted peers.
