Different transforms are compared to extract bit sequences used in secret-key binding for highly-correlated physical-identifier outputs. A set of transforms that perform well in terms of decorrelation efficiency is applied to ring oscillator (RO) outputs to improve the reliability and uniqueness of the extracted sequence, information leakage to an eavesdropper about the secret key and RO outputs, secret-key length, and hardware cost.

We propose a simple protocol which allows two legitimate parties to exchange some confidential message over a wireless
channel with some chosen level of semantic security against passive eavesdroppers, and without needing either secret or public keys. The proposed method leverages the noisy and fading nature of the channel and exploits coding and all-or-nothing transforms to achieve the desired level of semantic security. We also define suitable metrics to estimate the semantic security level in the considered setting.
