Technical Summary This document defines the PA-TNC protocol. PA-TNC is a Posture Attribute protocol that carries posture attributes between a Posture Collector on a NEA client and a Posture Validator on a NEA server. The PA-TNC protocol is designed to run over the PB-TNC protocol. PA-TNC is equivalent to the Trusted Computing Group's IF-M 1.0 protocol. It addresses the PA protocol requirements defined in the NEA requirements specification. Working Group Summary The WG solicited proposals for the PA protocol based on the NEA reference model and requirements specified in RFC 5209. The TCG submitted a specification to the NEA WG in response to the call for proposals. There was broad support in the WG to adopt the submission as a WG document. Subsequent WG updates to the document have not been contentious. The protocol document specifies a base protocol and is extensible. The WG has discussed the potential for certain optimizations and extensions to the above specifications (e.g. additional standard posture attributes). The proposed extensions did not share the same level of consensus as the base document and represented significant additional work. The WG decided to defer potential extensions to supplemental documents in the interests of making progress on the base documents. Document Quality Several vendors have indicated their intention in public or private to implement the specification. Personnel Susan Thomson is the document shepherd. Tim Polk is the responsible Area Director.
