ENHANCMENT OF AES ALGORITHM FOR IAX PROTOCOL

Abstract

Voice over IP (VoIP) is transforming the telecommunication industry. It

offers multiple opportunities such as lower call fees, convergence of voice and

data networks, simplification of deployment, and greater integration with

multiple applications that offer enhanced multimedia functionality. However,

notwithstanding all these technological and economic opportunities, VoIP also

brings up new challenges. Among them, security is perhaps the most

compelling. Security for Voice over IP (VoIP) can be achieved in different

ways. In this project new encryption algorithm has been proposed and

implemented on IAX protocol with focusing on the performance for the secure

media session. But VoIP has a very special characteristic: it is “time critical”.

Time has a tremendous impact on this technology’s ability to performance, and

to transmit meaningful information as well. Consequently, security

considerations for VoIP must take additional steps to fulfill specific quality

demands.]1[
