TC and Identity Management – a Use Case Scenario  Title:
SCENARIO DESCRIPTION
 Requirements Analysis

 

Scenario Description

The scenario is based on the notions mentioned in section 8.4.3, but refers also to other parts of the deliverable. It emphasizes the need for cross identification of users between different identity domains. 


Fig7: Identification across different Identifier Domains [140] 

 

In this scenario, there exist two Identifier Domains, IDom1 and IDom2. In each identifier domain, there is a Service Provider (SP) and an Identity Provider (IP). The IP can issue identity credentials to a user who wants to gain access to the service inside the same identifier domain.  

In principle, an SP in IDom1 can validate credentials that have been issued only by an IP inside the same IDom1. However, in certain business use cases, an SP in IDom2 should be also able to validate credentials issued by an IP in IDom2. For that, this SP should be able to verify the trustworthiness of the IP in IDom2, and whether the authentication policy allows this IP to issue this kind of credentials which are valid for both identifier domains.
