Has there been any progress on that since then? This is also blocking
the inclusion of GnuTLS v3; we're currently shipping 2.12 which is a
year out of date and lacking some important features and fixes.
The GnuTLS maintainer has clarified¹ that he has *only* used parts of EC
which are documented in RFC6090 — a document which was produced
*specifically* to cover the unpatented parts of Elliptic Curve
cryptography, and which has no normative references dated later than
1994. It even eschews the definitions of MAY/SHOULD/MUST etc. from
RFC2119 and provides its own, because RFC2119 was published later than
For GnuTLS at least, the approval should be fairly much a no-brainer.

could somebody please look at this one and expedite the response to
this. There are a few valid points there and this seems rather urgent,
considering out-datedness and the bug fixes found in updated versions.
In particular section 9 in RFC 6090 (page.20).
Quote: "Concerns about intellectual property have slowed the adoption of
ECC because a number of optimizations and specialized algorithms have
been patented in recent years.
All of the normative references for ECDH (as defined in Section 4)
were published during or before 1989, and those for KT-I were
published during or before May 1994. All of the normative text for
these algorithms is based solely on their respective references."
Somebody will have to look at this closer to figure out, if the 17 year
or the 20 year expiration period applies.
