Abstract
Abstract. Trust management is currently being tackled from two different perspectives: a “strong and crisp ” approach, where decisions are founded on logical rules and verifiable properties encoded in digital credentials, and a “soft and social ” approach, based on reputation measures gathered and shared by a distributed community.
