SYSTEM AND METHOD FOR VERIFYING TRUSTED STATUS OF PEER IN PEER-TO-PEER NETWORK ENVIRONMENT

摘要

PURPOSE: A system and a method for verifying the trusted status of a peer in peer-to-peer network environment are provided to verify that the peer is a trusted peer using signed receipts in the peer-to-peer network environment. CONSTITUTION: A service requesting peer generates and broadcasts an "I need" packet over a network(582). The service requesting peer awaits an "I have" response communication from a service server on the network(584). If the digital certificate of the response communication is not or cannot be verified(586), the service requesting peer optionally places a responding server peer in a "black list" and reports the responding server peer in a next report(588). If the digital certificate of the response communication is verified(586), the service requesting peer preferably generates and broadcasts an "I found" message(590). The service requesting peer forwards a file to be uploaded to the responding service server at an alias URL specified in the response communication(592).
