Abstract
In this paper, we implemented the conference system based on DTLS for saving securely the VoIP, which is served sprightly in the latest, securely and tested (and also analyzed) the system. As VoIP technology development, demand of conference system is increased and the related technologies are growed. But Security protocol to protect conference service is getting late than conference technology. In this paper, we studied based on DTLS protocol that can provide function of signaling, channel security, media channel security and application of group key and apply to VoIP conference system based UDP unchanged. In this paper, we searched suggested security protocols based on DTLS can apply to conference system and implement and apply the protocol to conference system. And we tested (and also alayzed) overhead of encryption and key management mechanism.
