A Secure Cloud Computing System by Using Encryption and Access Control Model

Cloud computing is the concept of providing information technology services on the Internet, such as software,hardware, networking, and storage. These services can be accessed anywhere at any time on a pay-per-use basis. However, storing data on servers is a challenging aspect of cloud computing. This paper utilizes cryptographyand access control to ensure the confidentiality, integrity, and proper control of access to sensitive data. Wepropose a model that can protect data in cloud computing. Our model is designed by using an enhanced RSAencryption algorithm and a combination of role-based access control model with extensible access controlmarkup language (XACML) to facilitate security and allow data access. This paper proposes a model that usescryptography concepts to store data in cloud computing and allows data access through the access controlmodel with minimum time and cost for encryption and decryption.
