A Trust Router is an infrastucture element used to construct multihop Application Bridging for Federated Authentication Beyond the Web (ABFAB) federations. This document defines both the Trust Router Protocol and the Temporary Identity Protocol, which can be used together to enable multihop ABFAB federations without requiring a centralized Public Key Infrastructure (PKI).
