An Efficient Access Control Mechanism for Application Software Using the Open Authentication
As the cloud service is developing, technologies such as virtualization/big data processing is being proposed, but security accidents are occurring constantly. Therefore, companies which are afraid of disclosure of their main data build their own private cloud service. However, in the virtualization software, it is difficult to control the execution of application software and there are also other issues, such as system resource waste, repeated user login execution. Hence, this paper considers executing application software in accordance with the user privilege, by using the Open Authentication and the virtualization technology. For this purpose, a proposed system was designed and implemented, and it was verified by simulation that the proposed system reduced the system resource usage and could execute application software on Web according to the user privilege. Our proposed scheme can support another private cloud service such as SaaS more efficiently.
