METHOD FOR PROVISIONING CRYPTOGRAPHIC KEYS DURING MANUFACTURING

摘要

A method of manufacturing a computing device is provided that allows the computing device to generate a secret value, where any one manufacturer of the computing device lacks sufficient information to determine the secret value. The method may include manufacturing a processor and injecting a first random seed into the processor at a first manufacturing location. After assembling the processor with other hardware components onto a PCB, a second random seed may be injected at a second manufacturing location. After injection of the random seeds, the processor may execute instructions to combine the seeds to generate the secret value.
