摘要/Abstract

摘要：

针对传统授权域共享机制不能控制数字内容只被域内指定设备共享，从而不支持域内个性化共享的问题，提出了一种基于密文策略属性基加密的共享模型．该模型为授权域内相同个性化共享需求的设备建立一个与属性相对应的逻辑“子授权域”，并用指定子授权域的属性来加密数字内容许可，确保了只有指定子授权域内的设备可以共享该数字内容，从而有效地支持域内设备的个性化共享．

关键词: 数字版权管理, 授权域, 属性基加密, 个性化共享

Abstract:

According to the problem that the traditional sharing mechanism in the authorized domain does not enable special devices in the authorized domain to share special digital content, so that individuation sharing in the authorized domain is not supported. A ciphytext-policy attribute-based encryption based DRM sharing model is proposed. Devices of the same individuation sharing requirement are organized as an attribute-related logical sub-domain, and the license is encrypted under the attribute in the special sub-domain, so that only devices in the special sub-domain can share special digital content, and individuation sharing in the authorized domain is achieved.

Key words: DRM, authorized domain, attribute-based encryption, individuation sharing
