“…While we have only touched upon some of the issues necessary for deploying Merkle hash tree based authentication schemes for adaptive multimedia content in this short paper, an extended article is available (Kaced and Moissinac, 2006b) that provides more details, including: a deeper look at Merkle tree maintenance, algorithms for the verification procedures, and experiments and experiences with an actual implementation.…”

“…XSST allows both Proxy and Server sign the messages, this signature can be generated directly by the proxy and server, or by other applications which the XSST interacts with. More informations about XSST can be found in (Kaced and Moissinac, 2006b). Figure 3 illustrates the operations between the multimedia server S and the proxy P, and the operations between the proxy P and the client C for requesting and adapting the multimedia data.…”

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.

Multimedia services such as Internet streaming and video conferencing are increasingly getting very popular among all sectors of society and all ages. Many users rely on these services for activities related to their work, education, and entertainment. Users typically receive multimedia content over open network channels, where malicious attackers could potentially intercept and manipulate such content for political, financial or other reasons. Therefore, ensuring the authenticity of received multimedia streams is clearly an important problem. This chapter first proposes a set of requirements that an authentication scheme designed for multimedia streams should meet. It then surveys the most important schemes in the literature for authenticating non-scalable as well as scalable multimedia streams. Unlike non-scalable streams, scalable streams provide flexible adaptation to accommodate the dynamic network conditions and the diversity of receiving devices. Moreover, the chapter presents a qualitative comparison among the presented schemes using the proposed set of requirements, and it outlines potential directions for future research on authentication of multimedia streams. 4.

“…Content delivery (or distribution) network technologies have been investigated for years and have evolved to incorporate content adaptation management mechanisms into the exiting infrastructure [7], [8]. Though many technologies from different aspects of the content delivery chain need to be addressed separately, such as context collection and representation, adaptation algorithm and its execution, adaptation decision-making etc., the biggest challenge remains as the infrastructure design where content adaptation can be carried out with efficiency as well as flexibility.…”

“…If it is on a proxy (e.g. [8]), the adaptation of the content could be clearly separated from both the user and the content provider. This allows the user and the provider to focus on their own jobs.…”

With increasing diversity and heterogeneity of content access devices and network technologies as well as user preferences, content delivery has evolved into a matter of ubiquitous service where production, delivery and access of content form major challenges for content provider, network operator and user respectively. Content adaptation has been widely acknowledged as one of the most important aspects for ubiquitous content delivery. Incorporating content adaptation into content delivery network has been intensively investigated in recent years, but still remains as a big challenge due to not only the technology heterogeneity and complexity, but also the deployment implication facing the different players in the content delivery chain, e.g. content provider, network operator, user, third-party service provider. This implication is caused by the lack of infrastructural support for content adaptation in traditional content delivery network. This paper presents the design of such an infrastructure, called Adaptation Management Framework (AMF). More importantly, this design targets its application in a distributed manner to allow content adaptation take place across the content delivery chain. A working cycle of content adaptation under the infrastructure is described, and performances evaluation and analysis are presented in terms of scalability.
