Probabilistic assessment of security services in dynamic environments with non-trusted parties

The security attributes (confidentiality, integrity and availability) of services have traditionally only been expressed as qualitative issues. Some research on applying the dependability paradigm to security has been done during the past decade. In the dependability community, quantitative methods for assessing the attributes of dependability, i.e. reliability, availability and safety, are well-known and considered reasonably effective. A successful application of methods from the dependability area to assess the security attributes of systems will potentially lead to significant progress in the work of adding security to the Quality of Service architecture. This research will therefore focus on how to model and analyse security by means of dependability methodology. Adequate network QoS, including security, will be decisive with respect to the establishment and maintenance of trust in fair and equal conditions for partners in a competitive economic system, to protect intellectual property or to contribute to the overall acceptance of the ubiquitous use of ICT among the general public. The study and development of principles and methods for establishing models for handling trust relationships in complex scenarios involving advanced network services in dynamic networks with mobile users are included in the project.
