We were confronted with the task of creating and implementing this kind of secure system, running on myHelp.gv.at, which is one of the Austrian e- Government Portals. The solution - or as we call it `proxy authenticator' - enables us to omit any alterations to existing protocol structures or to amend the software architecture for all Austrian e-government applications.enProxy Authenticator - Approach of a Signature-based Single Sign On Solution for E-Government ServicesText/Conference Paper1617-5468
