Aggregating trust using triangular norms in the keynote trust management system

Research output: Chapter in Book/Report/Conference proceedingsConference proceedingpeer-review

Abstract

A Trust Management model that provides a measure of the degree to which a principal is trusted for some action is proposed. At the heart of the model is the notion that triangular norms and conorms provide a natural and consistent interpretation for trust aggregation across delegation chains. It is argued that specifying how trust is aggregated is as important as specifying a degree of trust value in an attribute certificate and, therefore, in stating the degree to which a principal trusts another, the principal should also state how that trust may aggregate across delegation chains. The model is illustrated and has been implemented using a modified, but backwards-compatible, version of the KeyNote Trust Management system.
