Absorbing Heinrich Isaac

Johann Heinrich Dierbach (1788–1845)

his eighties. In 1835, he married and settled in Paris as a teacher at the Conservatoire des Arts et Metiers, while conducting agricultural experiments with his brother-in-law on an estate in the Alsace, which was sustained economically by revenues from oil-bearing sands. Although McCosh's account of the collaboration with Dumas and the fat controversy with Liebig does not replace that given by...

AB - compacta Isaac

We define a compactum X to be AB-compact if the cofinality of the character χ(x, Y ) is countable whenever x ∈ Y and Y ⊂ X. It is a natural open question if every AB-compactum is necessarily first countable. We strengthen several results from [Arhangel’skii and Buzyakova, Convergence in compacta and linear Lindelöfness, Comment. Math. Univ. Carolin. 39 (1998), no. 1, 159–166] by proving the fol...

Distinguishing attacks on ISAAC

This paper presents two strong distinguishers for the deterministic random bit generator ISAAC, requiring 2 and 2 samples of respectively 64 and 32 bits, based on the observation that more than 2 167 initial states among the 2 192 ones induce a strongly non-uniform distribution of the bits produced at the first round of the algorithm. A previous attack on ISAAC presented at Asiacrypt’06 by Paul...

Isaac Keslassy - PhD Thesis

The function of a router is to switch arriving packets to their correct output destination. A router is built to achieve a specified capacity (the sum of the rates of its interfaces), and users expect a router to consistently achieve this capacity. However, no commercial high-speed router can guarantee today that it will achieve its full capacity for all arrival traffic patterns. This is due to...
