A Secure Sharing System for Cloud Desktop Applications Migrating with Optimized User Experience

摘要

It is becoming easy to share cloud based desktop applications for group work among multiple users accessing them from any locations by advances in virtualization technology. This kind of sharing requires a secure mechanism for authenticating users to provide a good user experience under the group work. We have been developing a secure sharing system for cloud desktop applications migrating with those requirements. The proposed system includes a user authority authentication mechanism using attribute-based encryption and IP mobility mechanism migrating desktop applications from the current cloud to the other one to improve the quality of the user's interaction. This paper describes implementation of the proposed system and the specification of a prototype system.
