  • System and method for non-bypassable and unclonable microelectronic device fingerprinting
    Patent number: 12585833
    Abstract: A method for provisioning a microelectronic (ME) component or device for non-bypassable, unclonable electronic device fingerprinting includes receiving an initialization vector from a provisioning device. A physically unclonable function (PUF) incorporated into the ME device (and unique to that ME device) provides a unique device bitstream. The device bitstream and initialization vector are cryptographically hashed to generate an electronic device fingerprint recordable to non-volatile memory onboard the ME device, which can be used for subsequent verification that the ME device is not counterfeited or compromised.
    Type: Grant

  • System and method for secure and flexible key schedule generation
    Patent number: 7970133
    Abstract: The present invention is a method for secure and flexible key schedule generation, which includes loading a key schedule algorithm and a cryptographic algorithm into a cryptographic engine. The method further includes loading the cryptographic algorithm, when selected, into a cryptographic co-processor. The method further includes loading the key schedule algorithm into a separate virtual machine.
