A perspective on TINA service security architecture

TINA-C (Telecommunication Information Network Architecture Consortium) is a body of leading network operators and manufacturers world-wide, working toward an integrated information network architecture based on distributed, object-oriented technology. The distributed and open nature of TINA mandates service security as the inseparable part of TINA services. An architectural solution, called the `service transaction´, is proposed. Agreed security interests between the user and the provider are specified by the `security management context´, which provides a consistent quality of protection (QoP) over the multi-provider service domains. The key components of the TINA service security architecture are explained. The Common Security Service Object (CSSO) is explained, which provides an application-specific extension of the TINA security service
