| 摘要 |
A first processing system determines whether a second processing system provides a trustworthy state for supporting a virtual trusted platform module (TPM), based at least in part on an assertion made by a management authority. The first processing system also determines whether the management authority is trusted. The first processing system may transfer state for the virtual TPM to the second processing system only if (a) the management authority is trusted and (b) the assertion made by the management authority indicates that the second processing system provides a trustworthy environment for supporting the virtual TPM. In one embodiment, the first processing system transfers state for the virtual TPM to the second processing system only if a trust level designation for the second processing system is equal or greater than a trust level for the first processing system. Other embodiments are described and claimed.
