Abstract:
Physical Unclonable 1 Functions (PUFs) leverage manufacturing variations to generate device-specific keys during runtime only, overcoming the need for protection after power-off as for Non-Volatile Memory. The main challenges of PUF-based key storage are reliability of the response and sensitivity to Side- Channel Analysis (SCA). Oscillator-based PUFs are particularly sensitive to frequency spectrum SCA. Existing countermeasures can protect sign-based bit derivation that requires error co...     »
