The reference comes from RFC 5246 (TLS 1.2). In 2008 the specification was not withdrawn. > If someone wanted to propose an erratum that would fix this, I would be very > appreciative. Pointing out the problem is easy, but I don't know what to put in "It should say:". Pointing to SEC1 is not good if that is incompatible with NIST/ANSI. ISO and IEEE are behind paywalls. At this point it is probably best to wait for NIST SP 186-5 (NIST said earlier they hoped to release a draft version by May 2019, so I assume it will be released very soon). RFC 8422 is also referencing ANSI X9.62-2005 and would need a similar errata.

At the time when RFC 8446 was published, there was probably no quick and easy solution to the problem. But the fact that IETF has historically been fine with relying on specifications behind paywalls is part of the problem. If IETF had implemented a strong open-access policy a long-time ago, there would probably be an open-access version of ECDSA (NIST or IETF) a long time ago.. I agree with you about the policy here. To be honest, I just didn't notice this; and it would probably need some github spelunking to figure out the history of these references. If someone wanted to propose an erratum that would fix this, I would be very appreciative. -Ekr Cheers, John -----Original Message----- From: Dan Brown <danibr...@blackberry.com<mailto:danibr...@blackberry.com>> Date: Tuesday, 1 October 2019 at 12:47 To: John Mattsson <john.matts...@ericsson.com<mailto:john.matts...@ericsson.com>>, Peter Gutmann <pgut...@cs.auckland..ac.nz<mailto:pgut...@cs.auckland.ac.nz>>, Hubert Kario <hka...@redhat.com<mailto:hka...@redhat.com>>, "TLS@ietf.org<mailto:TLS@ietf.org>" <TLS@ietf.org<mailto:TLS@ietf.org>> Subject: Re: [TLS] Ecdsa-sig-value in TLS 1.3 – need for erratum? Re ECDSA specs and paywells: ANSI X9.62-2005 was withdrawn in 2015, expiring automatically after 10 years, despite my weak effort. A revival, ANSI X9.142, with almost the same content is under way, though even its fate is unsure. Also, I expect FIPS 186-5 is nearly ready, and will specify much of ECDSA and EdDSA (not ASN.1?), which many may like (even better than ANSI). Meanwhile, SEC1, versions 1.0 and 2.0, are available, fortunately or not, despite my weak effort. IETF has specs for sigs and their formats already, no? Then there's ISO, IEEE, ...

I think references to specifications behind paywalls and other types of limited access is a major problem. Not only for the standardization process, but also for researchers and implementors. In general, I think people should be able to implement and analyze IETF standards without having to pay for access. Open-access is even more important for security specifications. ANSI X.62 is hopefully quite well-studied, but for other references, the lack of analysis often leads to mistakes and unknown weaknesses. I would like the IETF to take a much stronger stance against normative references to paywalls.
