The notion of trust is fundamental in inter-domain Authentication protocols. The goal of this paper is to Develop an effective formalism for explicit expressions of trust relations between entities involved in authentication protocols. Different relevant types of trust are identified and classified. A formalism for expressing trust relations is presented along with an algorithm for deriving trust relations from recommendations. The advantages of that approach are demonstrated by analyzing and comparing the trust relation requirements of a few known authentication protocols.
