SYSTEM AND METHOD FOR SECURE BOOT ACROSS A PLURALITY OF PROCESSORS

摘要

A system and method for secure boot across a plurality of processors are provided. With the system and method, boot code is partitioned into a plurality of boot code partitions. Processors of a multiprocessor system are selected to be boot processors and are each provided with a boot code partition to execute in a predetermined boot code sequence. Each processor executes its boot code partition in accordance with the boot code sequence and signals to a next processor the successful and uncompromised execution of its boot code partition. If any of the processors does not signal successful completion and/or uncompromised execution of its boot code partition, the boot operation fails. The processors may be arranged, with regard to the boot operation, in a daisy chain, ring, or master/slave arrangement, for example.
