Approved.

(Dying gasp.  Funny.  I am reminded of the old DCE system where “ping” responses where “indy” – I’m not dead yet. :)

Subject: [Tls-reg-review] Request to register TLS EXPORTER-BBF-Dying-Gasp label

Hello,

The Broadband Forum (BBF) would like to register the following TLS Exporter label:

  *   Value: EXPORTER-BBF-Dying-Gasp
  *   DTLS-OK: N (because the intended use exports material from TLS, not DTLS)
  *   Recommended: N
  *   Reference: TR-301 Issue 2 Amendment 1 (will be published at https://www.broadband-forum.org/technical/download/TR-301_Issue-2_Amendment-1.pdf<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.broadband-2Dforum.org_technical_download_TR-2D301-5FIssue-2D2-5FAmendment-2D1.pdf&d=DwMFaQ&c=96ZbZZcaMF4w0F4jpN6LZg&r=4LM0GbR0h9Fvx86FtsKI-w&m=9pL6elL5Igaw5L4RJ04fH_m3CxT0FCzeH9hgSa0RgMk&s=JqqO2kOcaBTIm_Yd4Ce6g6ZVdNJ-wpGRyddmLGGT7ns&e=>)
The referenced document is currently in the final stages of review but has not been published yet (the latest published version can be downloaded from https://www.broadband-forum.org/technical/download/TR-301_Issue-2_Corrigendum-1.pdf<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.broadband-2Dforum.org_technical_download_TR-2D301-5FIssue-2D2-5FCorrigendum-2D1.pdf&d=DwMFaQ&c=96ZbZZcaMF4w0F4jpN6LZg&r=4LM0GbR0h9Fvx86FtsKI-w&m=9pL6elL5Igaw5L4RJ04fH_m3CxT0FCzeH9hgSa0RgMk&s=9oJWCv67HmYee0EU0D6QOEYzqoR9dNFYY2AVzHDDs9E&e=>; the new version is due for publication in June 2020). One of the things delaying publication is that we want to register this label prior to publication!

We could supply the latest version of the document on request (but would need reassurance that it will be available only to the expert reviewers). However, maybe it will be sufficient to quote the relevant section from the current draft?

Please see below:
--------

8.1.1.2 Dying Gasp Message Format Version 1
...

R-265 The DPU and PMA MUST export the key used to generate the HMAC from the TLS connection supporting the current DPU/PMA NETCONF connection, using the keying material export function as defined in RFC 5705 with the following input parameters:

  *   Label = “EXPORTER-BBF-Dying-Gasp”
  *   Application context = “Dying-Gasp”
  *   Length = 32
--------

Thanks,
William Lupton
