Abstract
Physical Unclonable Functions (PUFs) are a resource for generating and sharing secret keys.
The mutual information between two respective observations of the same PUF gives an upper bound for the achievable secret-key rate of a secret-sharing scheme that relies on this PUF.
This mutual information can be increased by including side information about the source.
We show for a given statistical model of the SRAM-PUFs, how side information can be estimated from multiple observations of an SRAM cell. Finally, we calculate the achievable increased secret-key rate given the estimated side information.
