Secure Cloud Storage System by Integrating Trust with Role Based Access Control and Cryptographic Algorithm

Abstract

Cloud computing is becoming the growing and advanced field in Information Technology. It is providing services to an organization over a network with the ability to increase and decrease their service requirements. These services are established and provided by a third party, who have their own infrastructure. It’s having a number of benefits but most organizations are worried due to security issues and challengesof the cloud. The security required at the bussiness level forces to design models that solve the organizational and dispense aspects of information usage. These models need to present the security policies plan to protect information against illegal access and modification stored in a cloud. The paper describes the way for designing the security requirements from the view of tasks done in an organization by using the cryptographic concepts to store data on the cloud in less time and cost for the process of encryption and decryption. In this paper, the RSA and AES algorithms are used for encryption and decryption of data. The role-based access control is used for providing accessibility according to the role assigned to the user. This system provides the rights for uploading to the user when that person is authorized by the Owner or Administrator.
