Abstract
A file may be transferred from one processor-based system to another. The file may include executable binary data together with an integrated digital signature. Each time a receiving processor-based system boots, the digital signature is automatically applied to the payload to ensure its authenticity. If the file is determined during the boot process to be corrupted, it may be automatically deleted and replaced with a predecessor file that may be maintained on the receiving system.
