A key based security mechanism for payment status in cloud service access control system

Cloud computing is widely accepted dominant paradigm that provides a number of resources and cost effective software services to their clients as they demand such as Software as a Service, Platform as a Service and Infrastructure as a Service. However these services provide a lot of benefits for their clients, but still there is a need of data security against unauthorized access of services (data). Access control is an important aspect of cloud computing to enhance the system security. This paper focus on securing the pay-as-you-go model used by cloud service access model (CSAC) using combination of RSA and AES algorithm to ensure that only authorized user access the services from cloud. It also provides the mechanism to detect the conflicts between policies and inhibits the access due to conflicts in the environment of cloud computing. This paper gives an insight into the enhancement of the security to access the services from cloud by proposed access control model. With this aim, this paper presents a secure access control model which allows legal access of services.
