Using of Wavelets for Secret Key Generation: A Measurement Based Study

For the physical layer (PHY) key generation, two distant nodes exploit the reciprocal channel coefficients as a shared secret. These nodes may obtain erroneous channel estimates and generate highly correlated but not identical secret keys. In this work, we analyze the key error rate (KER) performanc...

Description
Summary:	For the physical layer (PHY) key generation, two distant nodes exploit the reciprocal channel coefficients as a shared secret. These nodes may obtain erroneous channel estimates and generate highly correlated but not identical secret keys. In this work, we analyze the key error rate (KER) performances when different wavelet families are utilized as a pre-processing step in PHY key generation. Measurement-based KER results show that selection of the wavelet can significantly change the performance.
