Cloud data storage has provided significant benefits by allowing users to store massive amount of data on demand in a cost-effective manner. To protect the privacy of data stored in the cloud, cryptographic role-based access control (RBAC) schemes have been developed to ensure that the data can only be accessed by those who are allowed by access policies. However, these cryptographic approaches do...
Role-based access control (RBAC) model is a widely used access control model which can simplify security management in large-scale systems. Recently, several cryptographic RBAC schemes have been proposed to integrate cryptographic techniques with RBAC models to secure data storage in an outsourced environment such as a cloud. These schemes allow data to be encrypted in such a way that only the users...
