Problèmes de sécurité posés par les proxies d'adaptation multimédia : proposition de solutions pour une sécurisation de bout-en-bout

Abstract : Due to the growing number of exotic networks, hardware and software and the increased demand for using multimedia services comes a tremendous need for providing adaptation techniques that end to deliver an understandable content to heterogeneous clients. These last are, generally, characterized by particular constraints and limitations which make the use of rich content difficult, in addition to the unsupported functionalities by the environment. An adaptation method transforms the content from a state to another in order to meet the constraints of the client context. In some situations, several adaptations are applied on the original content to reach that goal, on the level system (ex: choice of flows), on the level of the organization of the data (ex: choice of level in a coding scalable), on the level of the modification of flows themselves (transcoding). Offering an adaptable content for users showed the need for defining techniques and practices concerning the security of the exchanges on the networks. Insofar as the multimedia adaptation of the documents requires authorizing the modification of these documents between the Servers and the end-users, it is necessary to study the necessary conditions to ensure these modifications in a protected way. We have to present a multimedia content delivery system that preserves the end-to-end authenticity of original content while allowing content adaptation by intermediaries. It is the general aims of this thesis.
