“…Even if the content is additionally encrypted, adaptation still can be done in the same way by simply discarding packets. This principle has already worked in IP-based networks as shown in [4,10]. Scalable content enables the design of an inherent ICN adaptation mechanism similar to network-inherent caching.…”

The consumption of audio-visual content is the most dominant traffic source in today's Internet. Novel architectural approaches, such as Information-Centric Networking (ICN), are developed to support efficient multimedia dissemination. As ICN and MPEG-DASH have several concepts in common, recent proposals consider a fusion of both technologies. However, MPEG-DASH relies on pure client-driven adaptation. This often rather selfish adaptation strategy inhibits benefits gained from ICN's inherent caching and multi-path transmission capabilities. In order to overcome this challenge, the contribution of this work is the integration of innetwork adaptation (INA) in ICN. We illustrate that INA can be realized despite ICN's content-based security model. Our proposal rests on scalable content, which enables INA without management and transmission overhead.

“…Moreover, these techniques do not consider the adaptability since they do not address encrypting scalable video contents. In contrast, the techniques reported in [11]- [13] ( [12] will be used throughout this paper) attempt to implement comprehensive security while retaining the in-network adaptability. Naturally, these techniques encrypt the payloads of each NAL unit while keeping the header information plain so that any in-network adaptation node can treat them as if they are not encrypted.…”

“…As the name implies, a trusted AE is the one that can make use of the security keys provided to it for decrypting a secured content, so as to be able to perform a number of both structural and signal-level content adaptation operations on the audiovisual media streams. With a similar analogy, an untrusted AE is a content adapting engine, with which a security key cannot be shared, and thus the content adaptation operation should be performed on the media stream blindly (that is to say, without decrypting the content) [12].…”

“…Since the video content has been encoded in a scalable format, this adaptation can be carried out by simply dropping parts of the content. Moreover, the video content is encrypted using the technology presented in [12], which allows adapting the encrypted contents without decrypting them. As a result, it is possible to use an untrusted AE to perform this adaptation.…”

Abstract-The wide range of media and consumer devices, currently available, has raised new security requirements for multimedia systems and their applications. Despite the wide variety of work conducted on the access control, Digital Rights Management (DRM) and adaptation areas to date, there is a lack of initiatives addressing them together. This article analyzes existing initiatives and proposes new technologies for the governed adaptations of secured content in heterogeneous environments. These technologies are integrated in an architecture for the secure management of multimedia contents, which covers the complete digital content value chain, from creation to consumption by end users. Video Surveillance is the application scenario chosen for further illustrating the use of the proposed architecture. Two use cases are discussed in order to address governance, protection and adaptation requirements in surveillance applications.

Abstract-As the extension of H.264/AVC standard, Scalable Video Coding (SVC) has achieved significant improvements in coding efficiency and scalability. Most of the available video encryption algorithms are designed based on H.264/AVC standard. In this paper, the extensional technologies in SVC relative to H.264/AVC are analyzed. According to the new characteristics, a scalable video encryption algorithm is proposed for H.264/SVC. Some new features, such as motion prediction information of spatial scalability and key picture information of MGS (medium-grain quality scalability), are encrypted with three domains in hierarchical layers using different keys. Performance analysis of the new algorithm is reported and its strength against cryptanalysis attacks is discussed. Experimental results indicate that our scheme has adequate performance to allow for its use in real world applications.
