Abstract:
In this paper, we develop and implement our Secure Universal Multimedia Access system (SUMA) for SVG content in the following three subtasks. For content adaptation, we based on XML/RDF, CC/PP and XSLT, for signing and authenticating SVG content we use Merkle hash tree technique and for content delivery, we develop a mechanism for dynamic delivery of multimedia content over wired/wireless network. We present Signature scheme and an access control system that can be used for controlling access to SVG documents. The first part of this paper briefly describes the access control model on which the system is based. The second part of this paper presents the design and implementation of SUMA adaptation engine. SUMA aims to deliver an end-to-end authenticity of original SVG 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 interme
diary proxies, transparently to connected hosts, which totally make abstraction of these processes.
