eccGnuPG

Hi,

The elliptic curve project to GnuPG has been moved to a new
server. Now the 
web address is:
http://www.calcurco
.cat/eccGnuPG/

And the sources patch sould be available in:
http://www.calcurco.cat/eccGnuPG/src/gnupg-1.4
.6-ecc0.1.6.diff.bz2

And the beta patch in:
http://www.calcurco.cat/eccGnuPG/src/gnup
g-1.4.6-ecc0.2.0beta1.diff.bz2

Have a nice hack

/Sergi.

Some people have asked me about ECC support in GnuTLS, and
your work
would provide a good foundation for that.  What is the
status of this
work?  Any chance ECC support will be integrated into
libgcrypt?

I am aware of some patent concerns, but I'm actively trying
to get
more information on the situation.

My last information is that we need to do the copyright
assignments.

However, calcurco.cat has only a pending registration, so
there is no
way to get its IP address.

The bad think is that I am not full time dedicated on a ecc.
As fas as I can, 
I want to port the code to libgcrypt (and also do a patch
for gpg2). But also 
there are some channel attack that I am working to prevent.

There exist patens over some algorithms, but not the ones
that are used on 
this module. At less, I think, it doesn't use anything
patented. ECDSA to 
sign and EC_Diffie-Hellman scheme plus an AES256 and a
SHA256 are the used 
algorithms.

This has been partially one.
Does not work yet.

bugs.gentoo.org/show_bug.cgi?id=159870

I will be happy if anyone has some thought regarding this.

Ok.  Other than the channel attack, are you aware of any
other known
problems with the patch?

I'd be willing to help with the libgcrypt port if you want.

You mean that IDEA is not supported by Libgcrypt?  That is
on purpose.
Nobody needs IDEA theese days and those who still want a 64
bit cipher
need to wait until the patent has expired.

There is a wealth of non-patented algorithms available for
years and
thus no need to pour money into the cash box of a company
which
seriously hindered the use of encryption over the last 15
years.


Shalom-Salam,

   Werner

The patch have one known problem published in the web. But
to day I receive 
the information that could be not accessible from every
where; I'm try to 
solve it as fast as possible.

The report say:
"Report de Gary D. Huffman, II a 9/Feb/2007:
"Corrupt messatges that broke instant messages between
to Jabber acounts using
"curves as a cypher system. It seems to happen more
frequently with small
"messages, but that may just be coincidence.

This is the great think of free software, if you want you
can. If you have 
knowledge on the library, you can try. Good results (tested
and this thinks) 
will be published. Also if you have some questions that I
can solve, no doubt 
to ask me. Happily I will answer to you!

Meanwhile I started to port the patch to libgcrypt.  Will
report as
soon as I have some success.
