基于查询属性基加密的访问控制方案

Searchable Attribute-based Encryption Access Control Scheme

针对医学影像数据云平台环境下数据安全和隐私保护问题,提出了基于CP-ABE的查询属性基加密访问控制方案.查询属性基加密融合了属性基加密方法和可搜索加密方法,使本文方案在有效阻止非授权访问的同时,提供密文查询功能,并且关键字密文可被多个用户共享检索.

To solve security and privacy problems of medical imaging cloud platform, this paper putsforward the access control mechanism with attribute-based searchable encryption based on ciphertext-policy attribute-based encryption(CP-ABE). The attribute-based searchable encryption is a combinationof attribute-based encryption and searchable encryption, which effectively prevents unauthorized accessand provides cryptograph query function,and the keyword cipher can be searched by multiple users.
