| Abstract: | In allusion to the deficiency of static identity authentication of modern distance education system using username/password based on MD5,the paper proposes a dynamic identity authentication technology based on grouping and disordering of MD5.The paper uses the method of probability and statistics to verify the security of this method and analyses the advantages of the method and finally gives the experiment. |
