CADENUS Security Considerations (abstract)

This paper deals with the development of security service provision required for end-user services in Premium IP networks that are being developed and tested within CADENUS project funded under an EU initiative. The initiative is focused towards setting up and experimenting with mechanisms that enable dynamic user-services creation, configuration and provisioning with in-built QoS. The authentication, authorization, data integrity and non-repudiation services are provided through exchange of information and documents between the mediators communicating with end user, the network resource manager and the service manager acting in the middleware part of a Premium IP network. The exchange is using the technology specified in the Extensible Markup Language (XML) messaging with the additions taken from the emerging Electronic Business XML (ebXML) model. The paper presents the XML/ebXML specified security mechanisms, which are in-built in the CADENUS architecture.
