Enforcing Role-Based Access Control for Secure Data Storage in Cloud Using Authentication and Encryption Techniques

With the fast advancement taking place in cloud computing and services, the culture to use the cloud for largescale data storage is being adopted. This growth in cloud computing has elevated the key security issue of how to control and avert illegitimate access to data stored in the cloud. Now a days most of the work concentrates on privacy of data contents and access control, whereas the attention towards privilege control is compensated. Role-based access control (RBAC) is one of the familiar access control model which provides flexible controls and database management by having users mapped to roles and roles mapped to privileges on data objects. In this paper, an encryption scheme is proposed which incorporates the cryptographic approaches with RBAC and also an anonymous control scheme to address the privacy in data as well as the user identity privacy in current access control schemes. A real-time method is provided to maintain a secure communication in cloud computing which ensures security as well as trust-based access to cloud. The proposed model contains algorithms to explain data protection and user authentication problems. The analysis suggests that the purpose of this work is carried out by the proposed algorithm i.e. to decrease cloud computing security concerns such as data protection, authentication, and securing data while communicating.
