Method and apparatus for secure computing device start up

Abstract:

The present invention provides methods and devices for secure computing device start up. The method includes generating a public/private key pair and signing a software image and obtaining a first time stamp and a second time stamp. The method further includes combining the signed software image, the first time stamp and the second time stamp into a bundle and deploying the bundle. During secure start up, the method includes authenticating the signed software image, the first time stamp and the second time stamp and booting the computing device if authentication passes. The computing device aborts booting the computing device if the authentication process fails.
