More and more modern group oriented collaborativeapplications use the peer-to-peer(P2P)paradigm tobe independent of expensive infrastructures as theyare,for instance,provided for audio and video conferencesby H.323 systems.Decentralized collaborativeP2P solutions require appropriate mechanismsto protect group privacy and data integrity.A centralizedclient/server based video conference system canbe well shielded in a standard manner,whilst thereare no off-the-shelf approaches to secure a P2P videoconference up to now.The paper addresses this issueand presents a flexible security architecture.Usingthe BRAVIS system[4]as an example it shows howthe architecture can be embedded into a P2P videoconferencing system.
More and more modem group oriented collaborative applications use the peer-to-peer (P2P) paradigm to be independent of expensive infrastructures as they are, for instance, provided for audio and video conferences by H.323 systems. Decentralized collaborative P2P solutions require appropriate mechanisms to protect group privacy and data integrity. A centralized client/server based video conference system can be well shielded in a standard manner, whilst there are no off-the-shelf approaches to secure a P2P video conference up to now. The paper addresses this issue and presents a flexible security architecture. Using the BRAV IS system [4] as an example it shows how the architecture can be embedded into a P2P video conferencing system.
