| Outline of Final Research Achievements |
The advantages provided by the cloud computing paradigm have led to a rapid adaptation, and a large number of cloud-based systems and services are in use today. However, recent results illustrate that the standard approach to securing these systems is insufficient due to the unique properties of a cloud-based environment, and attacks on real-world implementations have been demonstrated. This research develops encryption and authentication mechanisms, which are central to the construction of practical security systems, that address security concerns in a cloud-based system. Specifically, the focus is on security using weak or maliciously manipulated randomness and security against leakage and tampering attacks, which are relevant for both virtual machines providing a cloud service and the devices accessing this service.
