A Security Protocol For Real Time Applications(RTA)

Real time applications are growing rapidly in the recent past. In the recent times many business organizations have been deploying Real Time Applications over the internet like Video Conferencing, VOIP and other Multimedia services. These applications are used by thousand of users and controlled by different administrative entities The need to protect user's data and infrastructures becomes more important than ever. Cryptography is used to provide the security needed for real time applications. Since Real time applications contain confidential data, Current encryption techniques are not appropriate, because most of RTA is served via Internet; there is a need of strong security mechanism. In this paper a new security protocol called Real time security protocol (RTSP) is proposed. Experimental results show that the proposed model provides better security with minimum overhead in terms of processing
