摘要
提出了基于智能卡的数字电影版权管理方案。该方案将密钥数据存储于智能卡中并且解密运算全在卡内完成,与通用的软件方案相比提高了系统的安全性,用户认证时使用的是卡内信息而非用户信息或设备信息,不仅保护了用户隐私,还实现了权力转移的功能。开发了基于智能卡的数字电影DRM系统,实现了数字电影加密分发、授权和权利转移等系统功能,满足了数字电影版权保护的安全需求。
A digital rights management （DRM） system based on smart card is proposed for digital cinema （D-Cinema）. On one hand, as the calculations with key data are implemented inside the card, the security of system is enhanced. On another hand, since it uses data in smart card instead of user information or device information for user verification, not only the privacy of users will never be violated but also the rights transfer is realized. The DRM architecture is developed, and the functions ofdistribution ofencrypted digital movie, authorization and rights transfer are realized, which meets the security needs of digital movie.
