AN ANALYSIS OF VOICE OVER INTERNET PROTOCOL (VOIP) AND ITS SECURITY IMPLEMENTATION

Voice over Internet Protocol (VoIP) has been in existence for a number of years but only
quite recently has it developed into mass adoption. As VoIP technology penetrates
worldwide telecommunications markets, the advancements achieved in performance, cost
reduction, and feature supportmake VoIP a convincingproposition for service providers,
equipment manufacturers, and end users. Since the introduction of mass-market VoIP
services over broadband Internet in 2004, security and safeguarding are becoming a more
important obligation in VoIP solutions. The purpose of this final year project is to study
and analyze VoIP and implement the security aspect using Secure Real-time Transport
Protocol (SRTP) end-to-end media encryption in the Universiti Teknologi PETRONAS
(UTP) laboratory. Extensive research, evaluation of case studies, literature reviews,
network analysis, as well as testing and experimentation are the methods employed in
achieving a secure and reliable VoIP network. With the given time frame and adequate
resources, the study and analysis of VoIP and implementation of SRTP should prove to
be very successful.
