A Scalable Streaming Media Secure Communication Protocol Based on Bi-Direction Authentication

This paper presents a communication protocol of streaming media to ensure secure live transferring of scalable quality video programs over network. In our protocol, client, authentication server and video server collaborate for authentication, generation of session keys and transferring of encrypted streaming media. Bi-direction authentication is carried out by bi-direction challenge method and method base on public-key cryptography. Perfect forward secrecy is provided by adoption of Diffie-Hellman key exchange steps.
