摘　　要：数字版权管理系统旨在解决日益突出的数字版权问题,然而系统的认证环节却给用户带来安全隐患。针对解决系统用户安全问题进行研究,提出基于可信计算的数字版权管理系统。利用可信计算理论中的硬件级可信平台模块和直接匿名证明理论优化系统认证环节,对系统认证进行模型构建。通过ClearSight和SmartBits6000等设备构建仿真平台,仿真实验证明了理论的正确性,结果表明用户安全问题得到有效解决,数字管理体系更加全面、安全。The aim of Digital Right Management System （DRMS） is to solve the increasingly obvious digital right problems, but the authentication link of the system brings security risks to users. For studying the security issues of users, the article proposes a DRMS based on trusted computing. To optimize authentication link of the system, the paper makes use of trusted computing platform module in hardware level of trusted computing theories and direct anonymous attestation theory. Then the modeling for system authentication is carried out. Construction of simulation platform is based on equipments like ClearSight and SmartBits6000. The simulation experiments show that the theory is correct. The results show that the user security issues are effectively solved, the DRMS becomes more comprehensive and safe.
