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...
