The security application interface must be defined and enhanced to meet new requirements in the field of services delivery, security for and through the service. Pay-TV broadcasting and authentications for loggin have been the most studied secured multimedia mechanisms until now. The aim of this group is to enlarge those studies in a more general framework. The group intends to start the work with the development of a functional model for the securing of the multimedia chain, including the actors, the functions and the messages. An inventory of the existing cryptographic tools will then be performed. Finally, those tools will be extended in complex situations like CSCW or intelligent agents remote down-loading. In a general way, the conditional access to services will be considered through monitoring and/or filtering. This implies the consideration of the user authentification problematic. In the same time, the data flow authenticity and integrity have to be ensured. The security must be achieved but must also be managed. At the architecture level, interoperability has to be provided, thanks to the use of Trusted Third Parties for example. Audimetering and tracing are also part of it. It will be soon possible to down-load multimedia teleservices . This asks for securing during the down-loading as in cases of limited licenses or protection against viruses. The multimedia products owner asks also for security at the level of the copyright protection. In this field, the group will consider the applicability and the management of existing techniques like watermarking and labelling. Finally, some multimedia teleservices are related to a contract management (teleshopping, shared data, ...). It implies some specific security aspects which will also be considered by the group. These scopes will be studied in four communication configurations, namely, broadcast, client-server, CSCW and peer-to-peer. Chairman: Prof. Benoit Macq E-mail: Macq@tele.ucl.ac.be
