In recent years, the information protection for digital contents becomes an important issue for enterprise applications. To protect digital contents, various enterprise digital right management (E-DRM) schemes have been proposed to prevent the digital contents from illegal accesses. However, the previously related schemes did not support the digital right management for multi-user environments. In addition, these schemes are insecure in some applications. To overcome the above problems, we propose a new group-oriented E-DRM scheme with reliable and flexible access policies in this paper. The proposed scheme allows multiple users to acquire the access right, which can be dynamically determined according to the enterprise policy. In addition, no one can access the digital contents except authorized users. Compared with the related works, the proposed scheme is more reliable and flexible for enterprise applications.
