Abstract: In cloud computing and services with the rapid developments, there has been a growing trend to use the cloud for large-scale data storage. This has raised the important security issue of how to control and prevent unauthorized access to data stored in the cloud. Access control is one of the most important security mechanisms in cloud computing. By using the Role Based Access Control and Attribute Based Access Control, security to the data stored in cloud is enhanced through the fine grained access control policies. Attribute Based and Role Based Encryption techniques are used as the main encryption primitive. Signature Based authentication is used to improve security. Fine grained access control is provided with authentication that supports write privilege on outsourced data in cloud computing. Flexible authorization is provided by specifying the data user’s privileges and data owner’s policy in cloud computing environment. It provides integrity and scalability to the cloud storage systems efficiently and users will be accessing the cloud data securely.
I. INTRODUCTION
Cloud computing is the delivery of on-demand computing resources which include everything from applications to data centers over the Internet on a pay-for-use basis. Cloud computing is the result of evolution and adoption of existing technologies and paradigms. The goal of cloud computing is to allow users to take benefit from all of these technologies, without the need for deep knowledge about or…
