A federated Identity Management system (IdM) must include mobile units and must provide mutual authentication for client-server connections. Existing frameworks for identity management like SAML are unlikely to apply well to resource constrained mobile terminals like Android. The contribution of this paper is an IdM with simpler data representation and protocols for identity management and authentication, which can be deployed with fewer code lines, consume less bandwidth and require less connectivity than traditional protocols, e.g., those based on SAML and WSSec. The related service invocation mechanisms is designed to support mobile services, where object methods in mobile units can be invoked from other nodes in the network, regardless the use of NAT units and firewalls.
