We propose a streaming authentication scheme for the use over the IP telephony. To clear the strict real-time transmission requirements of the IP telephony, the latency and interval between signatures are adjusted dynamically according to the transmission quality of the network. This provides efficient signing and continuous authentication during real-time streaming. We show our scheme's advantages over previously proposed schemes by comparing delay on the sender and receiver side, and tolerance to packet loss.
