SVS - a secure scheme for video streaming using SRTP AES and DH.

Abstract

Video streaming technologies are becoming immensely important with the growth of the multimedia technology. With streaming, the end user can start watching the file almost as soon as it begins downloading. Security becomes a key problem to be handled when your valuable multimedia assets are floating over the network. This paper presents the key management and encryption mechanisms on the Video (Motion Picture + Sound) streams on un-trusted client-server network. As Network data Security is a burning issue and dominates the communication systems today, we present a novel security scheme, named as SVS (Secure Video Streaming) to securely transfer the valuable multimedia video streams on the un-trusted network using the authorization, key management, encryption, packetization and authentication schemes. The process of authorization is done by allowing the network access to only authorized users, keys are generated through DH (Diffie-Hellman) key exchange mechanism, AES (Advance Encryption Standard) algorithm is used for data encryption, and then encrypted data is embedded into the SRTP (Secure Real-Time Transport Protocol) header. The SRTCP (Secure Real-Time Transport Control Protocol) Sender and Receiver reports are also generated for data acknowledgement. A keyed-hash algorithm is used to generate the MAC (Message Authentication Code) for every SRTP packet. After undergoing all these processes, the data is finally traveling over the network media. As a result, we hopefully tend to apply the best possible security on multimedia streams traveling among the Networks.
