Searchable Attribute-based Encryption Access Control Scheme

To solve security and privacy problems of medical imaging cloud platform, this paper puts forward 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 combination of attribute-based encryption and searchable encryption, which effectively prevents unauthorized access and provides cryptograph query function,and the keyword cipher can be searched by multiple users.
