Abstract: An algorithm is presented that reconstructs the clock control sequence in the generalized shrinking generator in the presence of noise. The shrinking generator is first reduced to a step 1/step E generator, where E depends on the maximum length of runs of zeros in the output sequence of its clocking part. Then a directed depth-first like search for optimal and suboptimal paths in the edit distance matrix corresponding to the generator is performed. The permitted path weight deviation from the optimum is determined by the noise level in the statistical model of the generator. Since the algorithm is deterministic, the correct clock control sequence is guaranteed to be found, unlike many known algorithms of this kind. Experimental results show that the algorithm converges to the correct solution relatively fast even if the noise level is high.
