摘要：A system and method for secure and verified sharing of resources in a peer-to-

peer network environment to facilitate efficient use of bandwidth are disclosed. Themethod for securely sharing resources over a peer-to-peer network generally comprisesbroadcasting a request by a requesting peer for a resource over the peer-to-peernetwork where the resource is identified with a resource version identifier, receiving aresponse from a responding peer on the peer-to-peer network indicating that theresponding peer has the requested resource, retrieving the requested resource from theresponding peer, and verifying the retrieved resource by ensuring the retrieved resourcecontains the version identifier embedded therein. Preferably, the verifying also includesverifying a digital signature, such as a 1024-bit VeriSign digital certificate, of the retrievedresource to ensure integrity of the retrieved resource.
