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. The method for securely sharing resources over a peer-to-peer network generally comprises broadcasting a request by a requesting peer for a resource over the peer-to-peer network where the resource is identified with a resource version identifier, receiving a response from a responding peer on the peer-to-peer network indicating that the responding peer has the requested resource, retrieving the requested resource from the responding peer, and verifying the retrieved resource by ensuring the retrieved resource contains the version identifier embedded therein. Preferably, the verifying also includes verifying a digital signature, such as a 1024-bit VeriSign digital certificate, of the retrieved resource to ensure integrity of the retrieved resource.

What is claimed is: 1. A method for securely sharing resources over a peer-to-peer network, comprising: broadcasting a single request to a plurality of peers by a requesting peer for a resource over the peer-to-peer network wherein the request contains an identification of the resource and the resource identification contains a resource version identifier; receiving a response from a responding peer on the peer-to-peer network indicating that the responding peer has the requested resource; retrieving the requested resource from the responding peer; periodically broadcasting a single progress message including progress information to the plurality of peers indicating that the requested resource is in the process of being retrieved; verifying the retrieved resource by ensuring the retrieved resource contains the version identifier embedded therein; and informing a service server on the responding peer that a local copy of the retrieved resource now exists; wherein a file name of the retrieved resource indicates a version of the retrieved resource, a file added to the retrieved resource specifies an original name of the retrieved resource, and the original name is utilized to verify the file name of the retrieved resource. 2. The method for securely sharing resources over a peer-to-peer network of claim 1, wherein said verifying the retrieved resource further comprises verifying a digital signature of the retrieved resource to ensure integrity of the retrieved resource. 3. The method for securely sharing resources over a peer-to-peer network of claim 2, wherein said digital signature is a 1024-bit VeriSign digital certificate. 4. The method for securely sharing resources over a peer-to-peer network of claim 1, further comprising installing said resource. 5. The method for securely sharing resources over a peer-to-peer network of claim 1, further comprising retrieving a catalog containing a listing of resources. 6. The method for securely sharing resources over a peer-to-peer network of claim 5, further comprising comparing the listing of resources with resources installed at the requesting peer to determine which resources are to be requested over the peer-to-peer network. 7. The method for securely sharing resources over a peer-to-peer network of claim 6, further comprising requesting each resource to be requested in a separate transaction such that each resource to be requested may be retrieved from a same or different responding peer. 8. The method for securely sharing resources over a peer-to-peer network of claim 1, wherein the responding peer scans a list of local aliased copies to determine if the responding peer has a local version of the requested resource. 9. The method for securely sharing resources over a peer-to-peer network of claim 1, wherein the responding peer waits a predetermined period of time before responding that the responding resource has the requested resource. 10. The method for securely sharing resources over a peer-to-peer network of claim 9, wherein the predetermined period of time is randomly generated between 0 and 2000 milliseconds. 11. The method for securely sharing resources over a peer-to-peer network of claim 1, wherein, after receiving the response, the requesting peer broadcasts a message to the plurality of peers that the requested resource has been found. 12. A product updating service, comprising: automatically downloading a catalog containing a current listing of resources for a product at a predetermined time, each resource being identified by a resource version identifier; comparing the listing of resources in the catalog with resources installed at a node of a peer-to-peer network to determine which resources are to be requested over the peer-to-peer network; requesting each resource to be requested in a separate transaction over the peer-to-peer network, the request being made via a single broadcasted request to a plurality of peers; retrieving each resource to be requested in the peer-to-peer network and the Internet; periodically broadcasting, for each requested resource, a single progress message including progress information to the plurality of peers indicating that the requested resource is in the process of being retrieved; verifying each retrieved resource by ensuring the retrieved resource contains the version identifier embedded therein; and informing a service server on the responding peer that a local copy of each retrieved resource now exists; wherein the product updating service is operable such that, for each retrieved resource, a file name of the retrieved resource indicates a version of the retrieved resource, a file added to the retrieved resource specifies an original name of the retrieved resource, and the original name is utilized to verify the file name of the retrieved resource. 13. The product updating service of claim 12, wherein said verifying each retrieved resource further comprises verifying a digital signature of each retrieved resource to ensure integrity of the retrieved resource. 14. The product updating service of claim 13, wherein said digital signature is a 1024-bit VeriSign digital certificate. 15. The product updating service of claim 12, further comprising installing each of the retrieved resources. 16. The product updating service of claim 12, wherein each resource is digitally signed with a digital signature. 17. The product updating service of claim 16, wherein said digital signature is a 1024-bit VeriSign digital certificate. 18. A computer program product, comprising: computer code that broadcasts a single request to a plurality of peers by a requesting peer for a resource over a peer-to-peer network wherein the request contains an identification of the resource and the resource identification contains a resource version identifier; computer code that receives a response from a responding peer on the peer-to-peer network indicating that the responding peer has the requested resource; computer code that retrieves the requested resource from the responding peer; computer code that periodically broadcasts a single progress message including progress information to the plurality of peers indicating that the requested resource is in the process of being retrieved; computer code that verifies the retrieved resource by ensuring the retrieved resource contains the version identifier embedded therein; computer code that informs a service server on the responding peer that a local copy of the retrieved resource now exists; and a computer readable medium that stores said computer codes; wherein the computer program product is operable such that a file name of the retrieved resource indicates a version of the retrieved resource, a file added to the retrieved resource specifies an original name of the retrieved resource, and the original name is utilized to verify the file name of the retrieved resource. 19. The computer program product of claim 18, wherein said computer code that verifies the retrieved resource further comprises computer code that verifies a digital signature of the retrieved resource to ensure integrity of the retrieved resource. 20. The computer program product of claim 19, wherein said digital signature is a 1024-bit VeriSign digital certificate. 21. The computer program product of claim 18, further comprising computer code that installs said resource. 22. The computer program product of claim 18, further comprising computer code that retrieves a catalog containing a listing of resources. 23. The computer program product of claim 22, further comprising computer code that compares the listing of resources with resources installed at the requesting peer to determine which resources are to be requested over the peer-to-peer network. 24. The computer program product of claim 23, further comprising computer code that requests each resource to be requested in a separate transaction such that each resource to be requested may be retrieved from a same or different responding peer.
