TCvisor: A hypervisor level secure storage

In this paper, we present design and implementation of TCvisor, a new trusted hypervisor. To this end, TCvisor provides a secure storage with different isolated view per user by using para-passthrough and combined key. In this regard, virtualization technology of processors has been used for complete isolation from operating system. By combining TPM base key, user´s password and geo function key, TCvisor provides a secure storage in an environment with split data. We have applied feature wise security analysis TCvisor´s secure storage from software system layers point then we have compared performance of TCvisor to selected candidates of existing layers.
