Internal-state reconstruction method is a method for reconstructing the internal state of stream ciphers with time-variant tables. The key size and the key scheduling algorithm of stream ciphers with time-variant tables do not influence the time-complexity of internal-state reconstruction method. We have already proposed an efficient deterministic internal-state reconstruction method based on a tree-search algorithm. In this paper, we improve the method by applying probabilistic internal-state reconstruction method proposed by Goli\'{c}. The proposed method is most effective method in the all internal-state reconstruction methods. |
