Technical Summary
This document defines the PB-TNC protocol. PB-TNC is a Posture
Broker protocol that aggregates posture attributes between one or
more Posture Collectors on a NEA client and one or more Posture
Validators on a NEA server. PB-TNC is equivalent to the
Trusted Computing Group's IF-TNCCS 2.0 protocol. It addresses the PB
protocol requirements defined in the NEA requirements specification.
Working Group Summary
The WG solicited proposals for the PB 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. assertion attributes). The
proposed extensions did not share the same level of consensus as the
base document and also 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.
