Abstract ：In view of the security problem which is induced by the public network transmission in current B/S architecture system ，this paper proposes an identity authentication project which combines the static password and the dynamic password to realize one-time pad.It separates the authentication server and application server ，puts the static passwords identify in pri- vate safe channel which can protect the static password security effectively ，in addition dynamic password authentication is designed with the well-known Schnorr protocol ，in order to make the private key sensitive by adopting complex chaotic se- quence.Combined with Java applet technology and symmetrical DES encryption algorithms in the public network transmis- sion ，the system security is advanced.Some examples are tested and indicated this novel scheme is feasible and credible.
