Securely available credentials framework in cloud computing environments

Due to increasing uses of credentials like certificate through smart phones and smart pads for user authentication in various e-government services and online based financial sector, it is essential to have service provider systems, which allows to access services through a variety of devices. This paper analyzes problems and limitations of the current securely available credential standards. Furthermore, it is also our intention to design N-screen based securely available credential framework (SACF) for internet services that meets framework and protocol requirement of credentials in a cloud computing environments. We designed the secure SACF architecture in cloud computing environments, which not only provides more flexible credentials roaming and digital signing framework but also leads to safer credential management in operating various mobile devices such as smart phone, smart pad, etc.
