In the last years several EU Member States have rolled out smart-card based electronic ID (eID) solutions to their citizens.
Not all of these solutions are directly compatible to each other. However, with respect to the i2010 e-Government initiative
and the upcoming EU Services Directive, cross-border identification and authentication is now on the agenda of all EU Member
States. In this paper we present a smart-card based eID identification and authentication solution, which supports smart-cards
from different Member States. The proposed solution can be easily integrated into existing authentication and identity management
solutions and does not necessarily require any additional client software to be installed by citizens.
