Abstract

One disadvantage with current Federated Identity Management systems is the establishment of the federation is based on a preestablished relying relationship between Service Provider and Identity Provider. The contribution of this paper is a proposal for the integration of Federated Identity Management with Automated Trust Negotiation to establish a Dynamic Federation, which makes the sharing of user information among potential business partners easier and more flexible, and provides better protection of users' privacy at the same time. In this paper, the architecture, main information exchange protocol and prototype implementation of Dynamic Federation Framework are described in detail.
