Abstract

OpenID is an open, decentralized and URL-based standard for Single Sign-On (SSO) on the Internet. In addition, the new electronic identity card (“Neuer Personalausweis”, nPA) will be introduced in Germany in November 2010. This work shows the problems associated with OpenID and addresses possible solutions. There is also a discussion on how to improve the OpenID protocol by the combination of the nPA respectively the Restricted Identification (RI) with an OpenID identity. The concept of an OpenID provider with nPA support will be presented together with its precondition. The added value created by the combination of the two technologies nPA and OpenID in different directions is discussed.
