| Abstract: | A improved digital chaos algorithm in which float point arithmetic is replaced by integeral arithmetic is introduced, and the chaotic sequence is applied to the USB software dog. This paper analyzes the principle and process of the digital chaos USB software dog. This dissertation elaborated the data exchange between PC computer and USB software dog. At last the anti-circumvention performance of this design can be seen in the paper by analyzing the principle of a few typical decryption technology. |
