Flexible Verification of MPEG-4 Stream in Peer-to-Peer CDN

The current packet based stream authentication schemes provide effective and efficient authentication over a group of packets transmitted on erasure channels. However, by fixing the packets in transmission, any packet manipulation will cause authentication failure. In p2p content delivery network wh...

The current packet based stream authentication schemes provide effective and efficient authentication over a group of packets transmitted on erasure channels.

In p2p content delivery network where a proxy-in-the-middle is able to store, forward, transcode and transform the stream, previous schemes are simply unapplicable.
