Data protection and video conferencing are difficult to combine. 90% of all video conferences work with a central server/MCU/gatekeeper. This server bundles the individual video and audio streams of the participants and sends the bundled stream back to the participants. Of course, he has to decrypt and re-encrypt the streams. To do this, it is necessary to have the key. Here two weak points arise:
In server based systems there is simply no end-to-end encryption!
Since the key is centrally available, the server is a weak point. An attacker only needs to break into the server once and could thus decrypt the entire communication.
Furthermore, in server systems a participant is always authenticated against the server and not against the other participants. The identity of the participants can thus be falsified via a compromised server. The participants would also not notice if the communication was being intercepted.
Due to the point-to-point architecture, BRAVIS has managed to create a real end-to-end security. This consists of the components:
Point to Point Architecture (P2P)
Perfect forward secrecy (PFS)
The enhanced security package adds end-to-end authentication to the high level of security already provided in the business package, which also meets the requirements of the Data Protection Act in the medical sector or the demands of security agencies.
