Authentication Schemes for Session Passwords using Hybrid and Paired based Techniques

Abstract

Early we use Textual passwords as a security but these passwords are vulnerable to the various attacks like Dictionary attack, Shoulder surfing, eves dropping, etc. Further graphical passwords are coming to the existence but the graphical passwords have their own disadvantages like they require more time to Authenticate and the usability issues. Thus we proposed a session password scheme in which the passwords are used only once for each and when session is terminated the password is no longer in use. The proposed of session password scheme uses Text and colors for generating session password. Two session password schemes are used Hybrid Textual Authentication Scheme and Pair-based Authentication scheme.
