Attribute-based encryption (ABE) cryptographically implements finegrained access control on data. ...
Furthermore, ABE is the only cryptographic approach to fine-grained access control that does not require an online trusted third party during access requests, and thus provides better availability properties ...

In this paper, we address these problems by considering ciphertext-policy attribute-based encryption (CP-ABE), which is conceptually closer to the traditional access control methods such as RBAC. ...
So, for a large amount of EHRs, this scheme is not efficient. Furthermore, using RBAC for access policy makes the policy changing difficult. ...
They con-sidered two types of ABE schemes: key-policy ABE (KP-ABE) and CP-ABE to apply the fine-grained access control. ...

This is usually expected behaviour since CP-ABE is often used to cryptographically enforce access control policies and it is natural to assume that an entity is aware of their access rights. ...
In practice, it may be desirable to use a 'large universe' CP-ABE scheme, wherein arbitrary textual strings are mapped to attributes (group elements), e.g. using a hash function H. ...
