A SYSTEM AND METHOD TO ESTABLISH TRUSTED BOOT LOADER USING SELF-SUBSTANTIATED BOOT LOADER

摘要

The present invention provides a system and method for establishing a trusted boot loader using a self-substantiated boot loader in a computing platform. It is a Minimal Real-Time Operating System (RTOS) that loads and executes a trusted boot files and kernel modules. The system and method capture platform evidences from a client machine and a server machine, performs measurement on the integrity of the platform evidences to ensure that it is running on trusted slates, and updates the platform evidences and platform configurations to the server machine for validation. The platform evidences are updated in the client machine by downloading a plurality of instructions from the server machine. Any changes in the platform may show that the platform is compromise by unknown entities. The system runs as part of the boot loader modules to provide trusted environment to the operating system. The system and method is operable with or without TPM chip.
