Abstract:

This paper introduces some current dynamic password techniques, and emphasizes the identity authentication based on the time synchronization mechanism in these techniques. Then it introduces this method’s principle, work progress, and analyses its security and shortage. At last, it gives some solution schemes on its lack of defending second hand’s attack and time excursion to make it safer and perfect.

Key words: dynamic password, time synchronization, time excursion, SSL technique
