Trust and Reputation Systems for Autonomic Computing. In open and autonomic systems where peers are likely to found themselves disconnected from their preferred security infrastructures, the only form of trust possibly available to users might rest upon forms of reputation, i.e. a collective measure of trustworthiness computed on the basis of ratings from members of the community. The existence of many reputation systems with remarkable differences calls for frameworks for modeling, analyzing, implementing and comparing them. This project will tackle this problem through the development of a solid foundational framework. On the one hand, it will permit to formally model different reputation systems and reasoning on them. On the other hand, the considered reputation models will be implemented in an appropriate networked execution environment in order to assess their performances. The project will investigate the integration of different reputation models into autonomic systems to manage information coming from the (possibly unknown) execution environment.
