| Abstract(in English) | A random sequence is used in a stream cipher. For safety, it is important that an arbitrary subsequence cannot be inferred from a given subsequence. Generally, the inference requires linear feedback shift registers (FSR). Therefore, cryptanalysis becomes more difficult when nonlinearity of a random sequence is intensive. To measure nonlinearity, the number of registers required for a FSR is used. This evaluation measure is usually called linear complexity. This paper introduces a multi input-output FSR, and discusses its linear complexity, generation method of subsequences, and standard system structure. Then a multi-input-output FSR generates random sequences faster than a single input-output FSR of the same linear complexity. |
