A Survey on Different Authentication Schemes for Session Passwords

Abstract

To provide the security mainly authentication and authorisation is given to the system. For that purpose mostly textual passwords are being used. Now day’s graphical passwords are also available. The password schemes those are being used by now Days are mostly textual password and the graphical password (pattern matching), textual passwords are vulnerable to eves dropping, dictionary attacks, social engineering and shoulder surfing. Graphical passwords are introduced as alternative techniques to textual passwords. But Most of the graphical schemes are vulnerable to shoulder surfing. This paper shows the study of the available authentication schemes for session password.
