Time-Based Confidentiality Enhancement Scheme for Mobile Wireless Networks

TL;DR: A general approach to calculate the probability of intercepting enough shares by arbitrary nodes, together with simulations, shows that the probability is small and provides a valuable alternative for delay tolerant applications to enhance message confidentiality.

Steganography using Cryptography and Pseudo Random Numbers

TL;DR: How a simple LSB steganography technique in images can be complicated further using combination of Cryptography and Pseudo-random number generator.

Real Computations with Fake Numbers

TL;DR: The notions playing major roles in this theory of computation over the real numbers are described, with special emphasis on those which do not appear in discrete complexity theory -- and some of its results are reviewed.

Optimizing polynomials for floating-point implementation

TL;DR: An algorithm is presented that forces to zero the smaller coefficients of the initial polynomial thanks to a modified Remez algorithm targeting an incomplete monomial basis, resulting in polynomials with less coefficients than those obtained theusual way.

On-Line Difference Maximization

TL;DR: In this article, the authors consider a sequence of arbitrary distinct values arriving in random order, and devise strategies for selecting low values followed by high values in such a way as to maximize the expected gain in rank from low values to high values.
