Correlations in stream ciphers: a systems theory point of view
Sara D. Cardell, Gkrard Maze, Joachim Rosenthal, Urs Wagner · Zurich Open Repository and Archive (University of Zurich) · 2010
Given a sequence of some autonomous behavior, this sequence can be computed as the output of a linear system. If one receives a highly noisy sequence correlated with such a linear sequence, the problem we study is how to obtain the input of the linear system. We explain known correlation attacks in this general setting and we show types of autonomous behaviors which should be avoided.
