摘要
In one embodiment, a computing device receives an image that has been signed with a first key, wherein the image includes a first computational value associated with it. A second computational value associated with the image is determined and the image is signed with a second key to produce a signed image that includes both the first and second computational values. Prior to loading the dual-signed image, the computing device attempts to authenticate the dual-signed image using both the first and second computational values, and, if successful, loads and installs the dual-signed image.
