Abstract
A first machine (e.g., server VM) authenticates an untrusted second machine (e.g., new client VM) as a condition to performing or allowing a protected operation. Authentication information is written to a library using one mechanism, and then read from the library using another mechanism. One of the mechanisms is an untrusted mechanism employing the untrusted second machine, while the other is a trusted mechanism performed by the first machine either alone or in combination with a trusted management component that has privileged access to the library. If a written and read value match, it can be inferred that the second machine is authentic, because the trusted management component has accessed an existing library that is also separately accessed by the second machine.
