Abstract: Role-based encryption is a new cryptographic primitive that enables the role-based access control (RBAC) model for encrypted data in cloud storage environments. Compared with some other cryptographic access control technologies, such as attribute-based encryption (ABE), it can greatly relieve data owners from the heavy burden to define and manage access control policies. In this paper, we present a new generic construction of role-based encryption from inner-product encryption (IPE) and revocation encryption, with following two significant features: 1) it is the first adaptively secure role-based encryption scheme in the standard model; 2) it is more efficient than all of the previous role-based encryption constructions.
