A new cryptographic algorithm for the real time applications

Abstract

Recently, many companies have been deploying Real Time Applications (RTA) over the internet like VoIP, Video Conferencing and other Multimedia services. The need to protect user's data and infrastructures becomes more crucial than ever. Encryption is used to provide the security needed for real time applications. Since RTA contain high volume of data, classical encryption techniques are not appropriate, because most of RTA are served via Internet, the encryption and decryption techniques has to take minimal time to achieve acceptable end-to-end delay. In this paper, a new cryptographic algorithm is developed to improve the time for encryption and decryption of data of end-to-end delay and provide higher level of security.
