Abstract
A method is provided for authenticating two distinct objects using a single signature stored on one of the objects. On initiation of a hardware system a valid hash value can be generated based at least in part on a rootdisk file and a kernel can be modified to contain the valid hash value. On subsequent boots of the hardware system, the valid hash value stored within the kernel can be compared with a value of a potential rootdisk file and if the valid hash value and the rootdisk hash value match, the hardware system can proceed with the boot process.
