A security framework for mobile cloud applications

Mobile Cloud Computing is a new concept, which offers Cloud resources and services for mobile devices. It also brings several advantages to mobile devices and to the applications developed for them. However, it increases the security risks and privacy invasion due to the fact that it combines mobile devices with Cloud services and because there is not a well-defined application model. The security issues are treated independently and the existing security solutions are supplied separately by various providers. In this paper, we propose a framework to secure the data transmitted between the components of the same mobile cloud application; and to ensure the integrity of the applications at the installation on the mobile device and when being updated. Our framework allows applying different security properties to different kinds of data and not the same properties to all the data processed by the application. Also our approach takes into consideration the user preferences and the mobile device performances.
