Incentive Compatible Moving Target Defense against VM-Colocation Attacks in Clouds

Cloud computing has changed how services are provided and supported through the computing infrastructure. However, recent work [11] reveals that virtual machine (VM) colocation based side-channel attack can leak users privacy. Techniques have been developed against side-channel attacks. Some of them like NoHype remove the hypervisor layer, which suggests radically changes of the current cloud architecture. While some other techniques may require new processor design that is not immediately available to the cloud providers.
