摘要：In recent years, various enterprise digital right management (E-DRM) schemes have been proposed to protect and manage access rights of digital contents for the enterprise applications. However, we find that the previous E-DRM schemes do not protect the user privacy while mobile users access digital contents. In addition, the previous E-DRM schemes have high computation and communication loads. Besides, these schemes do not provide usage tracking for the digital content, and thus the digital right may be abused by malicious users. To solve the above problems, we propose a new E-DRM scheme with anonymous trust for mobile devices in this paper. The proposed scheme has low computation and commun ication loads, and it provides the user anon ymity and usage tracking. Therefore, the proposed scheme is more efficient and practical than the related works for E-DRM applications
