Research And Implement Of Double Authentication Scheme Based On Discrete Logarithm

Verifying the originality or truth of messages and authenticating the identity of the sender plays an important role in the protection of authorized user's rights and interests in the internet environment, for the number of the identity fraud cases is increasing. Double-authentication schedule based on discrete logarithm is put forward which combines DSA algorithm and a new algorithm studied in this paper. Double-authentication schedule prevents illegal users from cheating and denying. The main results of the research are shown as follows:1) putting forward double-authentication schedule based on discrete logarithm.2) putting forward algorithm used for Verifying the originality or truth of messages.3) implementing the main functions after system analyzing.4) deploying system and testing performance.
