Security of service requests for cloud based m-commerce

Cloud usage has already become a reality in users' everyday habits. Combining it with the wide adoption and use of mobile phones, mobile clouds seem to be the next step in mobile business. In our paper we analyze mobile cloud service requests with respect to the relevance they have for m-commerce and economy in large. We describe potential architecture solutions which include the use of UICCs (Universal Integrated Circuit Card). Finally, we illustrate the information flow of such a system with the example of mobile e-tickets and assess such architectures with respect to security, privacy and trust.
