Paper: Design of H.323 Secure IP-Telephony Framework

By | April 15, 2010

ABSTRACT
The paper is aimed to provide a secure IP-Telephony system based on H.323 set of protocols. H.323 is a standard that specifies the components and procedures that provide multimedia communication services—real-time audio, video, and data communications—over packet networks, including Internet protocol (IP)–based networks. H.323 is part of a family of ITU—T recommendations called H.32x that provides multimedia communication services over a variety of networks. From the security aspect, H.323 provides a scheme for authentication between the End Point (EP) and the GateKeeper (GK). However, the authentication between EPs lying on different GKs needs to be considered. Thus, the paper shows a proposed model and implementation with the evaluation of such authentication process. It also provides secrecy for certain users that require such a service. These have been provided by providing authentication for EPs laying on different GKs, as well as providing encryption for the voice data traveling between EPs laying on same GK or different GKs.

Keywords: Computer network, VoIP, IP-Telephony, H.323, and VoIP security.
