Abstract: A method and a discovery system are provided for discovering encrypted peer-to-peer (EP2P) nodes associated with a particular EP2P network. An EP2P connection request associated with the EP2P network is sent to each of a plurality of initial IP address and port number combinations. If an EP2P connection response associated with the EP2P network is received from a particular initial IP address and port number combination, it is determined to belong to an initial EP2P node associated with the EP2P network. An EP2P discovery request associated with the EP2P network is then sent to the particular initial IP address and port number combination, and an EP2P discovery response associated with the EP2P network is received. If the EP2P discovery response includes one or more new IP address and port number combinations, they are determined to belong to one or more new EP2P nodes associated with the EP2P network.
