Secure Password Authentication Scheme over Insecure Network

Abstract

Passwords are essential to ensure the privacy and security of personal data at home, at organization or World Wide Web. Simple passwords can be easily guessed and cracked with attacker’s experience. The better solution is to use One Time Password. Many researchers proposed the various password authentication schemes to be secure user login. However, the previous authentication schemes are neither efficient, nor invulnerable to various categories of attacks. The purpose of this paper is to overcome these problems. Ticket is created by third party (RC) for password secrecy and RC is structured for authentication. In this paper, a new Ticket oriented password authentication is proposed to achieve all proposed goals. Furthermore, this scheme also provides the integrity, confidentiality and mutual authentication.
