Title:
A Note on Automata-based Dynamic Convolutional Cryptosystems

Authors: Renji Tao

Abstract:

In [1],the automata-based dynamic convolutional cryptosystem is proposed and analyzed; the author claims that ``finding partial information about the cipher is quite easy, and the main idea of such an attack, described in detail in Section 4.1, is based on Gaussian elimination.‘’ But the deduction supporting this claim in Section 4.1 of [1] cannot work. It seems that this cipher is not so weak so far.
