Identity management and its support of multilateral security

We show our approach in developing an identity management system with respect to multilateral security. After examining digital pseudonyms and credentials as basic concepts of such a system, we give an introduction to technologies for multilateral security and describe an architecture which enables multilaterally secure communication. By means of di€erent scenarios we show requirements of an identity management system, and outline an approach in developing an identity manager and its infrastructure. Finally, we discuss problems and risks of identity management systems which must be considered when using such a system.
