Abstract
A processor of a device may provision a component of the device with a digital signature algorithm and an authentication key algorithm and/or server-provisioned private and/or public keys. The processor may generate one or more private keys and public keys and/or store them in a secure memory of the device. The processor may transmit the generated public keys to an owner server and receive a pedigree document in response, which may be signed with the private key. The owner server may determine a change in an ownership of the device and append the pedigree document in an immutable fashion in response to the determining to reflect the change in the ownership and/or sign the appended pedigree document with a private key. A chain of ownership of the device is verifiable using only information contained within the appended pedigree document and rooted in the processor itself.
