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 secretkey rate of a secretsharing 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 SRAMPUFs, how side information can be estimated from multiple observations of an SRAM cell. Finally, we calculate the achievable increased secretkey rate given the estimated side information.
