Abstract :
VoIP provides multimedia (audio and video, etc) services through Internet Network. Due to the characteristic of Internet, there are many attacks and threats in Internet, so are VoIP. Therefore, user authentication, confidentiality, and integrity of signaling message, media stream are required for secure communication. TLS and S/MIME are proposed for SIP signaling message protection and SRTP for media protection. MIKEY is also a standard protocol for key management. In this paper, we analyzed and implemented security protocols for VoIP. And then, we accomplished performance test of them by applying implemented security protocols to hardware VoIP phone and SIP proxy.
