Two novel authentication schemes for scalable multimedia streams over packet-lossy networks are proposed. The first scheme uses a digital signature to protect the integrity of a group of frames; the second scheme uses message authentication code to protect individual frame, making it packet loss-resilient and computationally efficient. Based on the second scheme, we propose a third scheme that provides authentication and collusion-free access control.
