A peer-to-peer network propagates searches from client to client. Resources within each client are selectively searched in response to authentication and authorization processes. Authentication information may be included in a search request or may be performed by an authentication process external to the client. Authorization is performed by a process external to the client. Only after authentication or authorization may resources of any particular client be accessed. The system allows for secure propagated searches and resource access in a peer-to-peer network environment. The network may further include a server for maintaining a list of clients connected to the peer-to-peer network in order to more efficiently facilitate peer-to-peer communications.
