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 (18091892)
