MAFTIA involved experts from 5 countries and 6 organisations. The Industrial Advisory Board provided valuable feedback on the work of the project.

Research was organised into six workpackages.

Birgit Pfitzmann (now at IBM Zurich), Michael Steiner (now at IBM Thomas Watson), and André Adelsbach led the research at Saarland.

Research at LAAS was led by David Powell and Yves Deswarte.

IBM Zurich
Michael Waidner, Marc Dacier (now at Institut Eurécom), Andreas Wespi and Christian Cachin led the work at IBM Zurich.

The Navigators Group, Universidade de Lisboa

The Navigators group, is one of the groups of (LASIGE), the Large-Scale Informatic Systems Laboratory, a research unit of the Department of Informatics of the Faculty of Sciences of the Universidade de Lisboa.

Lisbon was a major contributor to the conceptual model and architecture, and worked together with IBM Zurich and Newcastle to develop an intrusion-tolerant middleware. Throughout the project three key ideas on distributed systems architecture were explored:

We studied the concept of wormholes, which are enhanced subsystems that provide components with a means to obtain a few simple privileged functions and channels to other components, with "good" properties otherwise not guaranteed by the "normal" weak environment.

We explored the concept of architectural hybridization, a well-founded way to substantiate the provision of those "good" properties on "weak" environments. For example, the system can be augmented with a component that can be proved secure and timely (Trusted Timely Computing Base (TTCB)).

We investigated a new style of protocols for achieving intrusion tolerance, which for the most part execute in insecure environments, and resort to the TTCB only in crucial parts of their operation.
