Practical Implementations for Securing VoIP Enabled Mobile Devices

Abstract

Voice over Internet Protocol is the ability of transmitting Voice using the Internet protocol. This paper addresses an introduction to VoIP, threats of VoIP and studies previous works of secure VoIP. We also propose practical implementations for securing VoIP by using Java and Android. Finally we give security analysis of our implementation and analyze different protocols involved in making VoIP more secure by preventing from Man in the Middle attack by using a new MIKEY protocol.
