Abstract:
A system which provides remote attestation of a cloud infrastructure comprises a plurality of attestation servers, a virtual machine (VM), and a VM scheduler arranged to register the VM for attestation and deploy the VM to a VM host within the cloud. More than one of the plurality of attestation servers are selected and mapped to the deployed VM, and each of the more than one mapped attestation servers is arranged to collect perform remote attestations of the deployed VM and its VM host. Performing remote attestations comprises transmitting a request for trust evidence to the VM and VM host, receiving, storing trust evidence transmitted by the VM and VM host and transmitting VM and VM host trust evidence to a cloud user.

Claim (Index 22):
The method as claimed in  claim 18 , further comprising migrating the deployed VM from an original VM host to a destination VM host, the method comprising:\n retrieving the identity of the destination host using the VM scheduler; retrieving the identities of the plurality of mapped attestation servers using the VM scheduler; retrieving trust evidence for the original and destination VM hosts from the plurality of mapped attestation servers using the VM scheduler; preparing a migration of the VM to the destination host, using the VM scheduler; the step of preparing comprising; attesting the original VM host and transmitting original VM host trust evidence to the VM scheduler, using the plurality of mapped attestation servers; migrating the VM from the original VM host to the destination VM host, using the scheduler; informing the plurality of mapped attestation servers that the migration is complete, using the VM scheduler; instructing the plurality of mapped attestation servers to attest only the destination host; and attesting the destination VM host and transmitting destination VM host trust evidence to the VM scheduler, using the plurality of mapped attestation servers.
