Bad and Good Ways of Post-processing Biased Physical Random Numbers
Algorithmic post-processing is used to overcome statistical deficiencies of physical random number generators. We show that the quasigroup based approach for post-processing rando...

Biometric random number generators
Abstract Up to now biometric methods have been used in cryptography for authentication purposes. In this paper we propose to use biological data for generating sequences of random ...

Approximately achieving Gaussian relay network capacity with lattice codes
Abstract--Recently, it has been shown that a quantize-mapand-forward scheme approximately achieves (within a constant number of bits) the Gaussian relay network capacity for arbitr...

Exploiting Multiple-Antenna Diversity for Shared Secret Key Generation in Wireless Networks
—Generating a secret key between two parties by extracting the shared randomness in the wireless fading channel is an emerging area of research. Previous works focus mainly on si...

Bayesian Sampling and Ensemble Learning in Generative Topographic Mapping
Generative topographic mapping (GTM) is a statistical model to extract a hidden smooth manifold from data, like the self-organizing map (SOM). Although a deterministic search algo...
