● <strong>TreVisor</strong> is a ``thin hypervisor`` that encrypts hard<br />
disks transparently for the guest OS.<br />
● one unmodified guest, including Linux and Windows.<br />
● Most devices are just passed through, except<br />
● hard disk: hook into file access in order to en-/decrypt data<br />
transparently with TRESOR technology.<br />
● DMA devices: filter memory transfers by means of the<br />
IOMMU ; access to hyperspace is disallowed.<br />
