English abstract:
The cloud concept promises computing as a utility. More and more functions are moved to cloud environments. But this transition comes at a cost: Security and privacy solutions have to be adapted to new challenges in cloud environments. We investigate secret communication possibilities - data transmission concealing its mere existence or some of its characteristics - in clouds. The ability to establish such secret communication provides a powerful instrument to adversaries and can be used to gather information for attack preparation, to conceal the coordination of malicious instances or to leak sensitive data.
