✦ Synopsis


A statistical approach to cryptanalysis of a memoryless function of clock-controlled shift registers is introduced. In the case of zero-order correlation immunity, an algorithm for a shift register initial state reconstruction based on the sequence comparison concept is proposed. A constrained Levenshtein distance relevant for the cryptanalysis is defined and a novel recursive procedure for its efficient computation is derived. Preliminary experimental results are given and open theoretic problems are discussed.

## Abstract Family‐based association tests (FBATs) provide simple and powerful tests to detect association between a genetic marker and a disease‐susceptibility locus, manifest in subjects by a phenotype or disease trait. Here we propose a new class of conditional tests for family‐based association
