Web based security analysis of OPASS authentication schemes using mobile application

Abstract

Graphical password, text password are authentication of users on websites because of its simplicity and easy. User's passwords are easy to hack by using different malicious programs and threats. First, Users select easy to remember password because nowadays they using many accounts on different websites. To login to websites they need to remember all passwords.

Second, hackers can install malicious software to get the passwords, when user typing their username and password into unknown public computers. In this paper, developing web based security analysis of one Time password authentication schemes using mobile application. A user authentication protocol which involves user's cell phone and short message service to prevent password stealing and reuse attacks.
