Abstract
Peer-to-peer based live stream sharing platform is a novel technique for distributing visual data. Because of developments in computer equipment and network service, viewers can watch shows via the Internet rather than through the conventional broadcasted manner. Although data access via the Internet is more convenient, it is more difficult to manage the data transmission, and issues such as copyrighting become more of a problem. In this paper, we will propose an authentication scheme which accounts for this peer-topeer based structure and tolerates a large amount of participants. © 2008 IEEE.
