Cloud System provides an efficient way for storing the large amount of user’s data on the cloud. Due to this reason there has been growing trend to use the cloud for storing the large amount of data. This has raised the important security issue of how to control and prevent the unauthorized access to data which is stored on the cloud. One well known access control model is the Role Based Access Control (RBAC), which provides flexible controls and management by having two mapping, User to Role and Role to Privileges on data. RBAC is a well known access control model which can be used to protect the security of the cloud data storage. Although this cryptographic RBAC scheme have been developed recently to secure data which is outsourced by the owner of data on the cloud , but this scheme assumes there is existence of a trusted administrator who is managing all the users and the roles which is not realistic in large scale system. In this paper work we are going to implement the Role Based Encryption (RBE) scheme which can be efficiently implemented with the Role Based Access Control for storing the data on cloud securely. Based on the proposed scheme we present a secure RBE-based hybrid cloud storage architecture that allows an organization to store data securely in a public cloud, while maintaining the sensitive information related to the organization’s structure in a private cloud Also the size of the cipher text remain constant regardless of the no. of user’s in the particular role. User having higher role will be able to access the data of low level role’s data. Depending on the different condition different report will be generated
