A robust true random number generator (TRNG), able to assure high quality output at different working conditions, is an attractive solution in secure communication application, because it increasesâ€¦ (More)

We present an efficient numerical solution of a PDE-driven model for color image segmentation and give numerical examples of the results. The method combines the vector-valued Allen-Cahn phase fieldâ€¦ (More)

We quantify precisely the distribution of the output of a binary random number generator (RNG) after conditioning with a binary linear code generator matrix by showing the connection between theâ€¦ (More)

Digital notarization is one of the most promising services offered by modern blockchainbased solutions. We present a digital notary design with incremental security and cost reduced with respect toâ€¦ (More)

We show the connection between the Walsh spectrum of the output of a binary random number generator (RNG) and the bias of individual bits, and use this to show how previously known bounds on theâ€¦ (More)

We consider a bound on the bias reduction of a random number generator by processing based on binary linear codes. We introduce a new bound on the total variation distance of the processed outputâ€¦ (More)

In this brief, we present a <inline-formula> <tex-math notation="LaTeX">${16 \times 16}$ </tex-math></inline-formula>-pixel quantum random number generator (QRNG) based on Single-Photon Avalancheâ€¦ (More)

A statistical estimation algorithm of the weight distribution of a linear code is shown, based on using its generator matrix as a compression function on random bit strings.
