Private peer-to-peer

Private P2P networks are peer-to-peer (P2P) networks that only allow some mutually trusted computers to share files. This can be achieved by using a central server or hub to authenticate clients, in which case the functionality is similar to a private FTP server, but with files transferred directly between the clients. Alternatively, users can exchange passwords or keys with their friends to form a decentralized network. Private peer-to-peer networks can be classified as friend-to-friend (F2F) or group-based. Friend-to-friend networks only allow connections between users who know one another. Group-based networks allow any user to connect to any other, and thus they cannot grow in size without compromising their users' privacy. Some software, such as WASTE, can be configured to create either group-based or F2F networks.
