Design and Testing of two secure Video Conferencing applications based on JMF (Java Media Framework) and VIC (Video Conferencing Tool)

We present two secure real-time video conferencing solutions with JPEG coding using a cipher engine based on the Blowfish algorithm. One of these solutions is developed from Java media framework (JMF). In this case, our solution consists of encrypting frames coded with JPEG that are later encapsulated in packets of the RTP protocol (H. Schulzrinne et al., 1996) (real time transport protocol). Our cipher system is based on the Blowfish algorithm (B. Schneier, 1994) of the Cryptix open source cryptographic software library. Another solution is developed from VIC (video conferencing tool) (S. McCanne and V. Jacobson, 1995). In this case, our solution consists of encrypting the UDP packets that contain the JPEG coded frames incorporated in RTP packets. In this paper we analyse the solutions proposed and test the implementations developed in different data networks (LAN/WLAN, frame relay)
