New Approach to Strengthen the Password

Abstract

User authentication becomes more and more im-portant to protect the data of the users, with the rapid de-velopment of internet technologies, social networks, and other related areas. For legal users and defence against intruders password authentication is one of the widely used methods to achieve authentication. Many password cracking methods developed during the time, and people have been designing the counter measures against password cracking all the time. Many organizations enforce complicated password-creation rules and require that passwords include numeric and special characters to guard against such attacks. It has been already demonstrated that as long as passwords are not difficult to remember, they remain vulnerable to smart dictionary attacks. Using tools such as dictionaries or probabilistic models, attackers and password recovery tools reduces the number of attempts that are needed to guess a password. To move with this strategy we are presenting a password scheme that achieves this goal. The proposed system is based on intermixing between a fixed text (conventional part of a password) and a free random text (newly added) at different pre-defined indices having different per-defined lengths. The extension of the random text adds an additional level of difficulty in breaching the password. We also added three more techniques to strengthen the proposed password cheme. We are also using CAPTCHA, keystroke pattern and security que tions along with salt segment. We are trying to have more ecure y tem combining this four techniques.
