Abstract: We present the RIC (Runtime Attestation for I aas Clouds) system which uses timing-based attestation to verify the in- tegrity of a running Xen Hypervisor as well as the guest virtual machines running on top of it. As part of the RIC system we present a novel attestation technique which in- cludes not only the guest operating system's static code and read-only data sections but also the guest OS' dynamically loadable kernel modules. These attestations are conducted periodically at run-time to provide a stronger guarantee of correctness than that o ered by load-time veri cation tech- niques. A system such as RIC can be used in cloud comput- ing scenarios to verify the environment in which the cloud services ultimately run. Furthermore we o er a method to decrease the performance impact that this process has on the virtual machines that run the cloud services since these ser- vices often have very strict performance and availability re- quirements. This scheme e ectivel y extends the root of trust on the cloud machines from the Xen hypervisor upward to include the guest OS that runs within each virtual machine. This work represents an important step towards secure cloud computing platforms which can help cloud providers o er new services that require higher levels of security than are possible in cloud data centers today.
