Abstract:	The aim of this review is to study technologies involved in a video conference through Internet. Some security issues and solutions to them are also covered in this report. At first, several video conference environments are presented to clarify concepts. Also some commercial solutions are mentioned. Secondly, signalling protocols, specially SIP, are studied to be used in the set up of a video conference. Possibilities to secure SIP are also covered in the theoretical study. Thirdly, the Secure RTP protocol is presented to be used to protect the media flows. Then a key agreement mechanism, MIKEY, is stated to make the key agreement needed to establish a crypto session for SRTP. After the background study, an implementation of a secure video conferencing platform using miniSIP and RTP Packet Reflector is proposed. Then, the final implementation is detailed, showing up the problems appeared during this process and possible solutions to them. Possible new features for the system are also proposed. Finally, some measurement results taken using the new software are presented and analyzed.
