Abstract: A method and system is provided for enhancing an audio signal based on spectral subtraction. The noise power spectrum for each frame of an audio signal is dynamically estimated based on a plurality of signal power spectrum values computed from a corresponding plurality of adjacent frames. An over-subtraction factor is then dynamically computed for each frame based on the noise power spectrum estimated for the frame. The signal power spectrum of the audio signal at each frame is then reduced in accordance with the over-subtraction factor computed for the corresponding frame.

Abstract: Methods and systems related to producing chips with the uniqueness property are disclosed. A random bit vector is generated using a hardware random number generator on the chip or “on the fly” as a hardware component is being produced. The generated random bit vector is stored in a one-time programmable memory of the chip. A value is derived in the chip from the random bit vector programmed in the one-time programmable memory of the chip. The derived value is exported to an external receiving module communicably connected to the chip to enable a security application provider to encrypt a message that is decryptable by the chip using a key based on the random bit vector programmed in the one-time programmable memory of the chip.
