Secure network authentication with PassText

Roman V. Yampolskiy, University of Louisville


Network security partially depends on reliable user authentication; unfortunately currently used passwords are not completely secure. We have designed an authentication schema with a password, which is easy to remember and can be relatively quickly provided to the system, while at the same time remaining impossible to break with brute force alone. We have also proposed a novel measure of password length and compared password spaces of many popular alphanumeric and graphical authentication schémas against the one proposed in this paper.
