Modeling Content Protection

  • Eric DiehlEmail author


To model a system, the designer often analyses different points of view. Each model will represent one point of view. Using one single model is often insufficient for understanding the system. This is especially true for complex systems such as DRM. Currently, content protection models primarily address functional, transactional, and architectural points of view. The functional model describes the different functions of a system and the interactions between them. The transactional model defines the chaining of exchanged messages, of their steps. The architectural model maps the different elements of a system to actual principals such as servers, storage units, and devices. The four-layer model provides a security oriented view of the system.
