Abstract:
PhysicalUnclonableFunctions(PUFs)aresecurity primitives that have the capability of key generation on the fly. Ordering based Ring Oscillator (RO) PUFs are one of the best performing structures in terms of robustness, since key generation requires error-free bit streams. Even though many aspects of ordering based RO-PUFs have been analyzed in considerable detail in the literature, a full implementation has not been presented yet. Hence, the total area cost of the system is still in question. In this work, we first implement a conventional RO-PUF including an Error Correction Coding (ECC) block. Then, we present a full implementation of an ordering based RO-PUF. Finally, performance of conventional and ordering based RO-PUFs are compared and their advantages and disadvantages are discussed.
