A Secure Authentication Protocol for Cloud Services

The request about green IT technology is increasing recently. And effective use request of computer resource is increasing. So, necessity about Cloud computing is increasing rapidly thereby. However, Cloud computing environment have big security problems because embody using virtualization technology. It is Authentication that must solve in Cloud computing environment urgently. Therefore, we wishes to propose protocol that can solve suitable user and services certification in cloud computing environment. An novel authentication protocol that based on Kerberos. But it is faster than Kerberos and implement is easy.
