Description

The GÉANT Trust Broker (GNTB) was developed in response to the Open Call during the GN3plus project.

Aim of the GNTB project is the specification of a new automated metadata exchange service for large-scale authentication and authorization infrastructures, i.e., federations and inter-federations.

Trust Broker allows users to initiate the first-time contact between service providers (SPs) and identity providers (IDPs) to perform required preparations for identity data exchange in a fully automated manner.

This task will be carried out during the first year of GN4 with the aim to finalise any pending work and to prepare for a pilot.

The demo setup looks like following:

Demo setup

Motivation:

  • manual setup and IDP/SP configuration
  • aggregated metadata file
  • manual user attribute conversion
  • waiting time for users

Our goal:

  • let users trigger metadata exchange
  • extend existing workflows and protocols
  • automate configuration steps
  • standardization of the I-D DAME

Our approach:

GÉANT Trust Broker service

  • automates on-demand metadata exchange across federation borders
  • provides repository for user attribute conversion

Prepare the Pilot

This work item will work with possible pilot users to have a running pilot at the end of Phase 1. The work will include:

  • Improvements of the IDP implementation
  • Improvements of the TTP implementation
  • Documentation and deployment ready
  • Investigating the additional requirements of possible pilot users

3

Attribute Conversion

This work item will work with HEXAA in order to have solid ways for the integration of AAs. The work will include:

  • Improvements of the TTP implementation
  • Integration of AAs

Management

This work item will collaborate with SA5 and REFEDs in order to determine the futural collaboration. The goal of this non-official work item is to manage task 3, but also to explore the future path and improve the I-D together with IETF. The work will include:

  • Contact with SA5 and REFEDS
  • Improvements of the current I-D in collaboration with REFEDS, JRA3 and IETF
