I don't think this idea requires any cryptography; the verifier can simply ask a peer how much data it has received from each other peer. A peer could lie, saying that it received no data, but your certificates don't prevent that since a lying peer could just discard them. You might want to read up on Chunkyspread, Bullet, Bullet prime, and Chainsaw; some of these protocols can use tit-for-tat to provide incentives. http://iptps06.cs.ucsb.edu/papers/Venkat-chunky06.pdf http://www.eecs.harvard.edu/~mema/courses/cs264/papers/ multicastIncentives-p2pEcon04.pdf http://iptps05.cs.cornell.edu/PDFs/CameraReady_164.pdf http://www.cs.duke.edu/~vahdat/ps/bullet-sosp03.pdf http://www.cs.ucsd.edu/~jwanderson/bullet-usenix05.pdf Wes Felter - [EMAIL PROTECTED] - http://felter.org/wesley/ _______________________________________________ p2p-hackers mailing list [email protected] http://lists.zooko.com/mailman/listinfo/p2p-hackers
