  • Abstract
    A new post-processing scheme is proposed for Physical Unclonable Functions (PUFs) based on Ring Oscillators (ROs). The scheme uses the Discrete Cosine Transform (DCT) to decorrelate the RO outputs and improves on existing RO PUFs in terms of uniqueness and the number of extracted bits.
