  • Patent number: 10038445
    Abstract: A method for component authentication includes delaying an input signal along a first propagation path and a second propagation path, each propagation path including a same number of delay stages. A plurality of control inputs alters the first propagation path to include at least one delay stage from the second propagation path, and alters the second propagation path to include at least one delay stage from the first propagation path. A time difference between a first output of the first propagation path and a second output of the second propagation path is quantized into a plurality of time bins represented by a multi-bit output. The multi-bit output is transformed with a non-linear transform to provide a response output.
