The proposed paper, presents a new architecture on cloud platform which shifts
complete office to cloud. It includes building an application as office but emphasized more
on authentication function. It demonstrates the virtual organization on the cloud which provides
the virtual workspace environment to the registered user. The web based application
includes interactive services to users through the use of WebRTC and different web technologies.
Through the use of web services the security part is challenged. The basic aim of the
work is to build a strong security measure, authentication functions, to users for accessing
the “Office in the cloud”. Evaluation of services in terms of feasibility and quality is highlighted.
The proposed algorithm is checked with the existing algorithm which provides the security for applications on
the cloud. Two Way Encryption (TWE) authenticates the user to access the data stored on the cloud. Hence
the authentication is categorized in two ways as, user authentication and the application authentication, where
the organization is deployed on the private cloud.
