Research And Implementation Of PKI-Based DRM Interoperable System

With the rapid development of communication, the Internet and other electronic information technology, as well as the digital content itself is easy to spread facilitate replication characteristics, the spread of network-based digital media content has been more public recognition and welcome, especially the PC and the popularity of smart phonesso that the people can enjoy the convenience of digital content anywhere, anytime. But it is easy to copy, easy to spread, and protective digital media content, the copy is widespread dissemination of protected digital media content via the Internet, of these piracy as well as acts of infringement of intellectual property rights by the author will give relevant of bring huge economic losses, of combating digital media content producers actively hinder innovation and the generation of new content, hindering the development of the entire economic and cultural.The main works of this paper are as follows:Firstly, the study of the basic concepts and technical background of the DRM, the analysis of the composition of the existing DRM system, workflow as well as problems. Study the basic concepts of the PKI architecture, architecture, and security needs analysis.Secondly, for the shortcomings of existing DRM systems previously mentioned, given based on PKI DRM interoperability needs of the overall design of the system analysis the functional structure design, workflow, and system analysis. And DRM Bridge mechanism is introduced into the system to solve the problem of interoperability between different DRM device.Finally, based on the overall function of structural design, detailed design and analysis, completed to constitute a system of four modules based DRM interoperability PKI system design.PKI-based DRM interoperable system of new technology and mature DRM technology combine to take full advantage of the power of the PKI architecture certification integrity protection and confidentiality, by DRM bridge mechanism, digital rights protection while existing DRM system is to solve the problem of user privacy and content conversion.
