论文摘要
基于属性的加密（ABE）已成为一个以信息为中心的公共密钥加密系统，该系统允许数据所有者根据访问策略共享数据，而多个数据用户基于他们所拥有的属性，而不知道其身份。在原始安倍晋三计划中，中央当局根据数据用户的属性对系统进行管理，并向数据用户签发秘密密钥，所有者和用户都需要信任特定的CA。但是，在某些现实世界中，数据用户不会信任任何人，而是他们自己。对于这种情况，我们引入了ABE的新的权力下放模型，该模型称为数据用户基于数据的ABE（DU-ABE），该模型由数据用户共同管理。 Du-Abe是第一个分散的ABE计划，它在没有使用任何其他额外实体的情况下将当局取代当局。
Attribute-Based Encryption (ABE) has emerged as an information-centric public-key cryptographic system which allows a data owner to share data, according to access policy, with multiple data users based on the attributes they possess, without knowing their identities. In the original ABE schemes, a central authority administrates the system and issues secret keys to data users based on their attributes and both the owner and users need to trust a specific CA. However, in certain real-world applications, the data users would not trust anyone but themselves. For such situations, we introduce a new decentralization model of ABE, termed Data User-based ABE (DU-ABE), which is managed jointly by the data users. DU-ABE is the first decentralized ABE scheme that replaces the authorities with the data users without employing any other extra entities.
