This is interesting too: http://www.ietf.org/ietf/IPR/certicom-ipr-rfc-3446.pdf
This appears to be related to TLS.

What has Sun contributed to OpenSSL? I guess my question is this: If there are version of ECC that are developed and patented by Sun that have been given to the OS communities, either directly or through the OpenSSL license then can we use their implementation?
I wouldn't want to post any code that is not open source in our library which would includes IDEA, MDC2 and RC5.
If we find that ECC is only available to government users then I suggest we do not include it in our repository, the risk would be too great.
What we need to understand is what ECC technology is currently Open Source and can we do our own implementation and distribute it.

Certicom also holds patents on a number of ECC things (like almost all of ECMQV and things like point compression). NSA has licensed Certicom's ECC patents en masse for anything done on US Gov't contract.
There's a patent letter on the SECG website:
Part of the problem right now is that ECC work is a bit divided, which has made standardization a bit of a pain.

I'm not sure I understand this since SUN released ECC to the public domain. I'll get an opinion on it:

Keep in mind, however, that products violate patent restrictions,
not
implementations. Otherwise OpenSSL would not be able to include
IDEA,
MDC2 or RC5.
With all the discussion of FIPS 140, I had assumed that most
everyone
on the list is working on government contracts. Otherwise, why
bother
with it?
The NSA negotiated a blanket US Federal Government deal for Certicom's patent portfolio for use in ECDSA, ECDH and ECMQV.
So...
if you're a federal government agency, you get to use these algorithms without having to pay Certicom anything extra. So... if part of what you're hoping to do is to create an ECC
implementation
that can be used by a federal agency, then you can do so without
fear
of the Certicom lawyers. Now... the moment the implementation gets used in a commercial product, then you've got issues.

Is anyone working on Suite B stuff?
Rijndael is there, but it probably should be subclassed as AES
proper
if only to lock down the blocksize to 128 bits and the keysize
to
the
allowed 128 & 256 bits.
SHA256 is there, but it doesn't extent to cover the rest of the
SHA2
family (SHA384 and SHA512). SHA384 is part of Suite B.
Is anyone working on ECDSA, ECDH & ECMQV? (Well, given that
ECMQV
is
more heavily patent-encumbered in the US, I can understand if
it's
left by the wayside).
If not I might take a crack at a couple of pieces.
