1 Introduction

This document specifies the Device Trust Agreement Protocol (DTAG).

DTAG enables two UPnP endpoints to securely exchange certificates over an unsecure network and to establish a trust relationship by means of a simple, one-time shared secret.

DTAG is compliant with UPnP architecture and is implemented as a UPnP service [UPNPARCH1]. Therefore, this protocol does not have a specific WSDL declaration.

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
