Enhancing efficiency of enterprise digital rights management

Most of private enterprises and governmental institutions are in an increasing need for enterprise-oriented digital rights management (E-DRM) schemes. E-DRM schemes provide protection to digital contents that contain corporates´ sensitive information and prevent unauthorized access to these data. Previous work proposed a storage reliable and efficient E-DRM systems based on the information dispersal algorithm. In this paper, we propose a computationally enhanced information dispersal and reconstruction algorithms. We achieve significant reduction in the computational complexity without affecting the E-DRM system security and with comparable storage requirements.
