In this paper, we analyse security threats and security requirements about the designated PC solution which restricts usable PCs that are only an user own PCs or a registered PC for online banking or very important services. Accordingly, causable threats of the designated PC solution are classified a process, a network layer, a software module, and an environment of platform, and we draw security requirements based on analysed security threats. Results of this research are considered utilization of criteria for improving security of the designated PC solution and standards for giving hint of imposition of the designated PC solution.

Mobile devices have limited computing power and resources. Since mobile devices are equipped with rich network connectivity, an approach to subscribe cloud services can effectively remedy the problem, which is called Mobile Cloud Computing (MCC). Most works on MCC depend on a method to offload functional components at runtime. However, these works only consider the limited verion of offloading to a pre-defined, designated node. Moveover, there is the limitation of managing services subscribed by applications. To provide a comprehensive and practical solution for MCC, in this paper, we propose a self-stabilizing process and its management-related methods. The proposed process is based on an autonomic computing paradigm and works with diverse quality remedy actions such as migration or replicating services. And, we devise a pratical offloading mechanism which is still in an initial stage of the study. The proposed offloading mechanism is based on our proposed MCC meta-model. By adopting the self-stabilization process for MCC, many of the technical issues are effectively resolved, and mobile cloud environments can maintain consistent levels of quality in autonomous manner.
