Character-based online key management in cloud computing environment

Abstract

As an important part of DRM, key management technology has been widely used in protecting various copyrights, including industries such as digital television technologies. With the development of all kinds of technologies, the key management scheme has been developed and evolved within which the key distribution also has a variety of forms like unicast and multicast. In this paper, a key management scheme based on user role is proposed for the live video service on the cloud platform. The project provides the solution of key management in real time and security to some extent. According to the user role and service type in the actual occasions, we propose the scheme better adapted to the current scene based on the centralized logic key tree.
