Method and system for authentication of device using hardware DNA

A system for authenticating a device comprising:

• a transmitter configured to transmit energy towards the device at an angle of incidence;
• a receiver configured to monitor a response of the device to the energy transmitted towards the device at the angle of incidence;
• and
• a processor, coupled to the transmitter and the receiver, configured to:
• generate a signature of the device based on:
• the response of the device to the energy transmitted towards the device at the angle of incidence;
• and
• an inclination of the device relative to a horizontal axis when the device is exposed to the energy transmitted towards the device at the angle of incidence;
• compare the device signature to an enrolled signature for the device;
• and
• indicate that authentication of the device is successful when the generated signature matches the enrolled signature.

A method for authentication of a device, the method comprising:

• transmitting energy towards the device;
• monitoring a response of the device to the transmitted energy at each of a plurality of angles of incidence;
• generating a signature of the device based on:
• the response of the device to the transmitted energy at each of the plurality of angles of incidence;
• and
• an inclination of the device relative to a horizontal axis when the device is exposed to the transmitted energy;
• comparing the device signature to an enrolled signature for the device;
• and
• indicating that authentication of the device is successful when the generated signature matches the enrolled signature.
