Query: Reconstructing the Nonlinear Filter Function of LILI-128 Stream Cipher
  Based on Complexity   In this letter we assert that we have reconstructed the nonlinear filter
function of LILI-128 stream cipher on IBM notebook PC using MATLAB. Our
reconstruction need approximately 2^12~2^13 and the attack consumes 5825.016
sec (using tic and toc sentences of MATLAB) or 5825.016/3600=1.6181hours. We
got the expression of the nonlinear filter function fd of Lili-128 which has 46
items from liner items to nonlinear items based on complexity, the phase space
reconstruction, Clustering and nonlinear prediction. We have verified our
reconstruction result correctness by simulating the overview of Lili-128
keystream generators using our getting fd and implement designers reference
module of the Lili-128 stream cipher, and two methods produce the same
synchronous keystream sequence on same initial state, so that our research work
proves that the nonlinear filter function of LILI-128 stream cipher is
successfully reconstructed.
