Authenticating Streamed Data in the Presence of Random Packet Loss

  title={Authenticating Streamed Data in the Presence of Random Packet Loss},
  author={Philippe Golle and Nagendra Modadugu},
We propose a new scheme for authenticating streamed data delivered in real-time over an insecure network. The difficulty of signing live streams is twofold. First, authen tication must be efficient so the stream can be processed without delay. Secondly, authentication must be possible even if some packets in the sequence are missing. Streams of audio or video provide a good example. They must be processed in real-time and are commonly exchanged over UDP, with no guarantee that every packet will… CONTINUE READING
