OPASS Authentication Schemes Using Android Mobile Application in Providing Web Security

Popular form of authentication for user is through text password because of its effortlessness and convenience. On the other hand these passwords can be hacked by using malicious software and threads. Firstly, as users maintain several accounts on different websites they choose weak passwords which are easier to remember and they use same passwords for different websites. Reusing the same password for different websites may cause user to lose his information, if one account of user is hacked then hacker can gain access to all other accounts of user. Entering the passwords into public computers may not be safe if the attacker uses malicious software like keystroke logger to get users password. In this paper we design opass (one time password) authentication scheme for providing security to websites using an android mobile application. In this scheme we are using an android mobile and SMS (short message service) to prevent attacks while reusing passwords and stealing of passwords and to provide web security.
