Chaos-Based Content Distribution Framework for Digital Rights Management System

Multimedia contents are digitally utilized these days. Thus, the development of an effective method to access the content is becoming the topmost priority of the entertainment industry to protect the digital content from unauthorized access. Digital rights management (DRM) systems are the technique that makes digital content accessible only to the legal rights holders. As the Internet of Things environment is used in the distribution and access of digital content, a secure and efficient content delivery mechanism is also required. Keeping the focus on these points, this article proposes a content distribution framework for DRM system using chaotic map. Formal security verification under the random oracle model, which uncovers the proposed protocol's capability to resist the critical attacks is given. Moreover, simulation study for security verification is performed using the broadly accepted “automated validation of Internet security protocols and applications,” which indicates that the protocol is safe. Moreover, the detailed comparative study with related protocols demonstrates that it provides better security and improves the computational and communication efficiency.
