Abstract: A device specific key is generated within an electronic device by providing a challenge to a physically unclonable function (PUF) structure integrated within the electronic device, where the PUF structure outputs a specific response based upon a specific challenge provided to the PUF structure. The PUF response is provided to a cryptographic module integrated within the electronic device, and a device specific key is generated by the cryptographic module utilizing a cryptographic key generation algorithm. The device specific key is generated based upon a combination of input data including the PUF response and data that is specific to the electronic device.

Abstract: A system for electric power demand monitoring and control includes one or more data distribution networks interconnecting intelligent utility units located at customer homes with a host computer located in the utility company offices. Each intelligent utility unit is associated with a customer home for connecting and disconnecting a power service meter, monitoring customer demand, and controlling power to selected units. A network within the home interconnects each intelligent utility unit with power consuming units for providing data on power usage and power control. A data distribution network interconnects the plurality of intelligent utility units to the host computer as a head end unit, the data distribution network providing downstream communication channels from the host computer to the plurality of intelligent utility units and upstream communication channels from the plurality of intelligent utility units to the host computer.
