CrySTINA: Security in the Telecommunications Information Networking Architecture

TINA specifies an open architecture for telecommunication services in the broadband, multimedia, and information era. Its characteristics most relevant for security are a variety of services, a multitude of service providers, a well defined business model, a middleware platform for service development and provision, and the assumption of advanced costumer premises equipment. Concepts for its security architecture are developed in the CrySTINA project. We introduce the TINA-C architecture, analyse it with regard to security and present the CrySTINA security architecture. CrySTINA is aligned with the OMG's CORBA Security specification, but enhances it with regard to security interoperability despite the heterogeneity of security policies and technologies that must be expected in TINA networks. Thus, we present a model for the enforcement of security policies that supports the negotiation of security contexts.
