This document describes interaction models for remote attestation procedures (RATS). Three conveying mechanisms - Challenge/Response, Uni-Directional, and Streaming Remote Attestation - are illustrated and defined. Analogously, a general overview about the information elements typically used by corresponding conveyance protocols are highlighted. Privacy preserving conveyance of Evidence via Direct Anonymous Attestation is elaborated on for each interaction model, individually.
