EFFICIENT AND SECURE CONTENT PROCESSING AND DISTRIBUTION BY COOPERATIVE INTERMEDIARIES

Efficient and Secure Content Processing
and Distribution by Cooperative Intermediaries

Abstract:

                        Content services such as content filtering and transcoding adapt contents to meet system requirements, display capacities, or user preferences. Data security in such a framework is an important problem and crucial for many Web applications.

                        In this paper, we propose an approach that addresses data integrity and confidentiality in content adaptation and caching by intermediaries.

                        Our approach permits multiple intermediaries to simultaneously perform content services on different portions of the data. Our protocol supports decentralized proxy and key management and flexible delegation of services.

                         Our experimental results show that our approach is efficient and minimizes the amount of data transmitted across the network.

Existing Systems:

                         In order to enhance the performance of content distribution networks (CDNs), several approaches have been developed based on the use of data adaptation and content management services provided by intermediary proxies. In most of these approaches, content caching is the main service provided by proxies.

Proposed Systems:

            Our approach also assures data confidentiality during transmission. It highlights load distribution through P-proxies to improve system performance and supports parallel content services.

            Because no modification is required to current content distribution systems in order to adopt our approach, our work is easy to deploy for many applications. In addition, our approach is extensible; if a new type of content service is required, our architecture can be easily adapted to the new requirement.
