Mobile single sign-on systems against guessing attack

Abstract

Single sign-on system allows users to login networks for services with only a set of password. Many single sign-on solutions available today are lack of mobility or even insecure. In this article, we propose two new single sign-on solutions with the merits of mobility and resisting password guessing attack. The proposed first scheme is based on smart card, and the second one is based on password. Both the schemes are simple and practical for non-PKI users. © 2012 Springer Science+Business Media B.V.
