I've just posted another *Prototype* draft of HCD TNC Binding.

Note:  This version is technically complete (i.e., stable content
with no outstanding mapping or syntax issues).  This version is
ready for prototyping.

The changes in this version were almost all suggested during
recent discussions with Andreas Steffen of HSR University of
Applied Sciences, Rapperswil, Switzerland - project leader of
strongSWAN that includes open source implementations of
most TCG and IETF TNC protocols:


For review at IDS WG telecons.

- clean w/ line numbers

- redlines w/ line numbers

Change History

30 May 2015

Editorial – Revised section 2.3 TCG TNC Terminology to simplify AR, IMC,
and TNC Server definitions and to delete CESP, Flow Controller, MAP, MAP
Client, MAP Server, NAA, NAE, PTS, and Sensor (i.e., to remove definitions
that are not part of the IETF NEA TNC architecture)

Technical – Revised all HCD attributes defined in sections 5, 5.1, 5.2, and
5.3 to use only PWG standard PA subtypes defined in new section 9.1, per
Andreas Steffen

Editorial – Revised sections 5.1.10, 5.1.11, 5.2.3, 5.2.4, 5.2.7, and 5.2.8
on string and integer versions to name explicit internal fields in the
corresponding IETF PA-TNC attribute definitions and raise compliance to

Editorial – Revised section 5.1.15 TimeSource to correct hexadecimal value
to “0x17”, per Andreas Steffen

Editorial – Checked every hexadecimal and decimal value of PWG attributes
against PWG registry file again, per Andreas Steffen – TimeSource was the
only remaining error

Editorial – Revised section 5.4 Correlated Attributes to change “empty
string” to “empty string or all zeros integer” and clarify complete set
(PT-TLS) versus minimal set (PT-EAP) and transport-based conformance
requirements, per Andreas Steffen

Technical – Revised section 9 IANA and PWG Considerations to note
definitions of PWG standard PA subtypes, per Andreas Steffen

Technical – Added section 9.1 PWG Standard PA Subtypes to define HCD
components technically and numerically aligned with PWG Imaging System
State and Counter MIB (PWG 5106.3), per Andreas Steffen

Editorial – Revised section 10.1 Normative References to add PWG Counter
MIB (PWG 5106.3), update PWG Health Assessment Attributes (PWG 5110.1), and
delete TCG TNC Clientless Endpoint Support Profile (TNC-CESP)
