Abstract
A processing system with a trusted platform module (TPM) supports migration of digital keys. For instance, an application in the processing system may create a first configuration key as a child of a TPM storage root key (SRK) when the processing system has a first configuration. The application may also create an upgradable root user key associated with an upgrade authority as a child of the first configuration key. The application may also create a user key as a child of the upgradable root user key. When the processing system has a second configuration, the application may create a second configuration key as a child of the SRK. The application may request migration approval from the upgrade authority. In response to receiving the approval from the upgrade authority, the application may migrate the root user key to be a child of the second configuration key. Other embodiments are described and claimed.
