Heterogeneous Networks) is a tool under active development that supports a Bandwidth on Demand (BoD) service, intended to operate in a multi-domain environment using heterogeneous transmission technologies. The AutoBAHN system aims at providing a guaranteed capacity, connection-oriented service between two end points. Due to the level of access that the tool has to critical parts of the network, the importance of a trustworthy Authentication and Authorization Infrastructure (AAI) cannot be overestimated. This paper highlights the design and implementation for the Authentication and Authorization Infrastructure which is part of the AutoBAHN service and the decisions taken. The AAI is a service dedicated to enforce system security and to prevent unauthorized access and usage of resources. The BoD service modules may interact with AAI multiple times during a single request execution. After the initial authentication and authorisation check, the BoD system will apply additional, specific to BoD, rules and policies to the request. In addition, this paper presents the basic security aspects and components of the AutoBAHN system.
