Bistable Ring PUF

Recently a new PUF called the bistable ring PUF or BR-PUF was introduced. The BR-PUF is based on the idea that a ring of even number of inverters has two possible stable states. By duplicating the inverters and adding multiplexers between stages, it is possible to generate exponentially large number of challenge-response pairs from the BR-PUF.

Famous quotes containing the word ring:

    Ring out the old, ring in the new,
    Ring happy bells, across the snow:
    The year is going, let him go;
    Ring out the false, ring in the true.
    Alfred Tennyson (1809–1892)
