1TECHNIQUE OF USER AUTHENTICATION USING NUMERIC OTP
1. Summary
The increased use of different online services has presented a need to improve a secure
system. The system be designed in such a way that it would be able to authenticate and validate
the authorized user. In the recent times, several schemes of user authentication have been
developed. Various methods of authentication such as token based, biometric based and
knowledge based have been developed. The text-based system of passwords has been the major
method of security medium over the years. Although the text based system of verification has
been the base of authentication for several years, yet it has faced some drawbacks in the present
times. The report discusses on the various attacks that are attempted to crack the systems. There
are several attacks on the text based password method and graphical password techniques. The
different kinds of attacks that are faced are brute force attack, dictionary attacks, guessing,
spyware attacks, social engineering and shoulder surfing. The report provides a brief insight on
these various kinds of attacks and the way in which they are imposed. This report focusses on a
latest technique of the authentication of the user, which would be based on using a numeric
scheme of One Time Password (OTP). This new method of authentication has been widely
adopted by the government sector, banks and corporate sector based virtual private networks
(VPNs) so as to diminish the effects of the compromise of the password. It also discusses a
proposed algorithm model, which could be used in order to implement the newer technique of
this user authentication scheme.
2. Advantages and Disadvantages of One Time Password Scheme
This paper focusses on the new technique for authentication of a user, which may be
implemented in the new IT systems.
