Protecting Big Data in Public Cloud by Enhanced RBAC

摘要

The enterprise systems which runs in the public cloud environment are beyond the control ofthe users. However, the traditional access control methods which will be executed by the reference monitorson cloud server will not be trusted in future. Hence to protect the outsourced data an efficient method whichwill be used is self-contained scheme. This method will be developed by integrating the Role based accesscontrol with Cipher text policy attribute-based encryption which supports the fine-grained access policy.In this paper a security scheme is proposed and which protects the enterprise system called E_RBAC. Thedecryption and access control are enforced by CPABE and the authentication are done in the data. Theexperimental result shows the E_RBAC maintains efficiency, security of the data and the access controlwill get improved.
