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
