Challenge

Decision-making in a federated authorisation infrastructure should take into account the potentially conflicting goals of all the parties in the infrastructure and negotiate a solution that satisfies them all. This may require a solution that is not optimal, but ‘good enough’, and acceptable to all parties involved.

Relevance

In a self-adaptive federated authorisation infrastructure, it is expected for third parties to undergo some kind of change, for example, involving their goals or their deployment. This should have an impact on how the different parties collaborate in order to maximise each party self-interest. However, adaptation decisions that involve federated authorisation infrastructures may require negotiation between several stakeholders. If all the component systems’ goals cannot be satisfied, then a self-adaptive authorisation infrastructure may have to consider stopping its collaboration with some or all of the component systems with whom a compromise could not be reached.
