System and method for non-bypassable and unclonable microelectronic device fingerprinting

A method for provisioning a microelectronic component for device fingerprinting, the method comprising:

• receiving from a provisioning device, via a microelectronics (ME) device, a first initialization vector;
• obtaining a device bitstream via a physically unclonable function (PUF) unique to the ME device;
• generating, via the ME device, a hash output by combining the first initialization vector and the device bitstream via at least one first cryptographic hash function;
• transmitting the hash output to the provisioning device;
• obtaining, via the provisioning device, a second initialization vector;
• generating, via the provisioning device, a device fingerprint by combining the hash output and the second initialization vector via at least one second cryptographic function;
• and
• transmitting the device fingerprint to the ME device.

A method for provisioning a lot of microelectronic components for device fingerprinting, the method comprising:

• providing a set of N microelectronic (ME) devices, where N is a positive integer;
• sending, via a provisioning device, a first initialization vector to each of the N ME devices of the set;
• receiving, via the provisioning device, a hash output from each of the N ME devices of the set, each hash output received from an ME device of the set corresponding to a combination of the first initialization vector and a PUF bitstream unique to that ME device by at least one first cryptographic hash function;
• generating a device fingerprint for each of the N ME devices of the set by combining, via at least one second cryptographic hash function of the provisioning device, each hash output received from an ME device of the set and a second initialization vector;
• and
• sending, via the provisioning device, each generated device fingerprint to the corresponding ME device of the set.
