Abstract
One embodiment of the present invention includes a boot read only memory (ROM) with an embedded, private key provision key (KPK) set that enables secure provisioning of chips. As part of taping-out a chip, the chip provider establishes the KPK set and provides the boot ROM exclusive access to the KPK. For each Original Equipment Manufacturer (OEM), the chip provider assigns and discloses an OEM-specific KPK that is included in the KPK set at a particular KPK index. Upon receiving a secured provisioning image and the associated KPK index, the boot ROM accesses the KPK set to reconstruct the KPK and then decrypts and executes the secured provisioning image. Advantageously, this enables the manufacturing factory to provision the chip without the security risks attributable to conventional provisioning approaches that require disclosing security keys to the manufacturing factory.
