Abstract
Managing transfer of device ownership is provided. A digitally signed state change request for a device that includes at least one of a new device owner, a new designated successor device owner, and a new device ownership reversibility control bit is accepted. A stored state for the device that includes at least one of a current device owner, a previous device owner, a designated successor device owner, and a current device ownership reversibility control bit is read. The previous device owner is replaced with the current device owner, the current device owner is replaced with the new device owner, the designated successor device owner is replaced with the new designated successor device owner, and the new device ownership reversibility control bit is set in response to the new device ownership reversibility control bit being included in the digitally signed state change request.
