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. First, the technology requires a very low latency less than 150ms. Second, packet loss cannot exceed the mark of 3%. Third, the technology is highly sensitive to “unquantifiable disrupting factors such as jitter”. All these factors converge and constitute the most critical of all VoIP security vulnerabilities to ensure the secure stream of VoIP service and provide satisfactory performance.
