From the point of its users, federated identity systems provide great convenience to log in to varied web sites without bothering of registration in advance. Looking from a vantage point, federated identity management gives the opportunity to users of one IT system to access data and sources of another IT system seamlessly and securely without handling a complete user administration. Single signon mechanisms manage user authentication process of these systems prompting log in once and assure access control across those multiple independent systems. OpenID is a widely used federated identity/single sign-on scheme generally implemented with username-password authentication. In this work, we augment the user authentication phase of OpenID with certi cate-based authentication using smartcard technology. Our solution provides a secure method to authenticate the user with user's digital certi cate written on the smartcard.
