A STUDY ON IMPROVED OTP AUTHENTICATION SCHEME USING SYNCHRONIZATION SCHEME

The IT the industry develops and to follow it applies the techniques which are many even from financial field and it is strengthening a financial security. The OTP (One-Time Password) once after using, disuses with one time password with every session user to be immediacy, is and authenticated it is a means which is the possibility of receiving. The OTP is security technique from the Internet banking. The OTP of schedule one modification it creates and the asynchronous anger method which it uses compared to the synchronization method is more used. But the asynchronous occurred in server, and client for it increased an error range. The replay attack occurs consequently. The method which it sees consequently reduces an error range and the user authenticated securely.
