Abstract
In the past, the main purpose of telephony network is to transfer the voice. But Since 1990, there have been many changes about it. First of all, wireless mobile communication network has enjoyed tremendous growth at the popularity. And the purpose of communication has been changed to data communication from voice one. Furthermore, people have started to require both data communication and voice communication. Because of these issues, VoIP (Voice over IP) is getting to be a matter of concern. And According to development of network and computer devices, people want to communicate by not only voice telecommunication but also video telecommunication. However because it uses public IP network, security issues are getting to be an important thing in VoIP. Actually, there are many solutions to protect data from attackers in VoIP System. But to serve video transmission needs more special care. To display real time video streaming on telephones need more bandwidth and computing power. This is a handicap for video streaming on the mobile device. Therefore we concentrate on the solution how to protect the video data from attackers with well quality of service. This is discussed in this paper.
