Abstract
VoIP, which is used to deliver voice data on the Internet, is being welcomed as a means of replacing the PSTN. In VoIP, voice data are converted to Internet protocol data packets so that they can be delivered in an ordinary IP network. Thus, compared to ordinary telephone networks, it is low cost and highly extensible.
As VoIP services gradually gain traction, issues are coming to the fore, specifically security vulnerabilities and lowered service quality. To mitigate this, in this paper an authentication system is designed which an AA (Attribute Authority) server has added to VoIP in order to increase security and discriminate user access.
