| Abstract: | A software platform is brought forward,which can be used to generate and evaluate chaotic binary sequences.Three typical kinds of chaotic dynamics model are utilized to generate encryption sequences.On the basis of chaos map,a theory of block ciphers key space expand combined with the idea of "one-time pad" by shanon is constituted.The problem of "key space shortage" is successfully solved and a new DES algorithm based on chaos map is created. |

| Keywords: | chaos stream cipher one-time pad DES algorithm key space expand |
