A SECURE MEDIA STREAM COMMUNICATION FOR NEXT GENERATION NETWORK

Abstract

In NGN, the open interfaces and the IP protocol make the hazard of security aspect increased accordingly. Thereby, it is a very important premise for NGN network operation to afford a good secure media stream communication. In this paper, we will present a secure media stream communication for NGN. Then we will discuss the three parts of the media stream secure communication——media stream source authentication, secret key negotiation and distribution; media stream encryption/decryption in detail. It can effectively realize media stream end-to-end secure communication. Meanwhile, it also makes use of the expanding of former protocol during the secret key negotiation process.
