Abstract

Trust Management (TM) is a novel flexible approach to access control in distributed systems, where the access control decisions are based on the policy statements, called credentials, made by different principals and stored in a distributed manner. In this chapter we present an introduction to TM focusing on the role-based trust-management framework RT. In particular, we focus on RT0, the simplest representative of the RT family, and we describe in detail its syntax and semantics. We also present the solutions to the problem of credential discovery in distributed environments.
