With the proliferation of networked devices, today's multimedia applications operate, as never before, in heterogeneous and dynamic environments. An attractive way to deal with this situation is to make applications self-adaptive (or self-reconfigurable); that is, make them able to observe them-selves and their environment, to detect significant changes and to reconfigure their own behavior in QoS-specific ways. This issue has made the subject of numerous works, especially in the context of multimedia applications. However, several key requirements of adaptivity have not been well addressed such as: the generality to a wide range of applications, the customizability to each application context and the flexibility of reconfiguration mechanisms. We address these aspects in a component-based framework for building self-reconfigurable multimedia applications, named PLASMA. This paper describes the architecture of PLASMA and shows its use through an application use case. Experimental evaluations show that reconfigurations have a low cost, while significantly improving the QoS.

“…Various research works in proxy-based multimedia adaptation approach have been made in this area. Solutions proposed by (Johanson, 2001), Layaida (Layaida et al, 2004), use a proxy based adaptation for continuous data flow transcoding, other projects use a multi-proxy adaptation, Appat platform proposed by Lapeyre (Lapayre and Renard, 2005), ubiQoS presented by Bellavista (Bellavista et al, 2004). Unfortunately, these existing adaptation platforms do not address security and authentication of exchanged flows.…”

By breaking the end-to-end nature of the communication, proxies render the task of providing end-to-end security much harder or even impossible in some cases. In this paper, we will address the questions of when and how end-to-end security, like confidentiality and authenticity can be preserved, in a multimedia content delivery platform, when having one or more adaptation proxies in the data path. We describe SEMAFOR, a platform for protecting adaptive multimedia content delivery in heterogeneous environments. SEMAFOR aims to deliver an end-to-end authenticity of original content exchanged in a heterogeneous network while allowing content adaptation by intermediary proxies between the content transmitter and the final users. Adaptation and authentication management are done by the intermediary proxies, transparently to connected hosts, which totally make abstraction of these processes. SEMAFOR provides AMCA a new content authentication based on multi-hop signature scheme using a Merkle Hash Tree, and XSST a secured transaction protocol that gives securely exchanges of transactions in SEMAFOR.

“…Plusieurs études [3], [5], [6] ont démontré que dans le cas d'adaptation multimédia, l'adaptation au niveau intermédiaire était d'un apport considérable en terme de performance et d'efficacité, nous proposons donc une architecture d'adaptation basée sur des proxies d'adaptation.…”

Nous présentons dans cet article un système de sécurisation de flux multimédia qui a pour objectif de fournir une authentification de bout en bout de contenus multimédia échangés dans un réseau hétérogène tout en permettant une adaptation de contenu par des proxies intermédiaires entre les fournisseurs de contenu et les clients finaux. Nous avons proposé un prototype de système applicable à des contenus multimédia basés sur des métadonnées XML, dans lequel la signature des documents repose sur le standard W3C XML Signature. ABSTRACTIn this paper, we present a secured multimedia content delivery system that aims to deliver an end-to-end authenticity of original content exchanged in an heterogeneous network while allowing content adaptation by intermediary proxies between the content providers and the final users. We proposed a system prototype applicable to multimedia content meta-data written in XML, in which the signature of the documents rests on W3C XML Signature standard.
