| Abstract: |
| By combining with the properties of coding and statistic of the plaintext, we discussed the differential properties of the ciphertext sequences which are generated by a nonlinear combined generator. A difference attack algorithm which attacks the nonlinear combined sequences was proposed. In the end of the paper, an attack example of the difference attack algorithm was supplied. |
| Keywords: combined generator differential cryptanalysis differential positional set differential validity |
