From the discussions on the patenting of computer algorithms in this news
group a while ago, I learned that the RSA cryptosystem has been patented.
I did not follow the entire dicussion and do not know what has been
mentioned about the patent.  I have several questions about the patent.
Any help will be appreciated.

  1. Who now holds the patent of the RSA cryptosystem?
  2. When was the patent granted?
  3. Was the patent holder involved in the original developement of the
     cryptosystem?  If not, do the original developers of the crypto-
     system now hold any right to the cryptosystem?
  4. On what ground was the patent granted?  What aspects of the crypto-
     system and its application are covered by the patent?
  5. What are the implications of the patent on private/commercial uses
     of the cryptosystem?

The RFCs you want are RFC 1113 (PEM Encryption and Authentication), RFC 1114
(Certificate-Based Key Management) and 1115 (Algorithms, Modes, and
Identifiers).  

RSA will be selling a PEM toolkit, not a complete package, and I can't imagine
they will be releasing source code.  Trusted Information Systems in Glenwood,
MD is building a reference implementation whose source code (apparently 
including RSA) will be available on the Internet.

New drafts of the PEM RFCs were issued over the past few months, and PEM was
discussed at the IAB (IETF?) meeting a few weeks ago.  There should be one
more final version of the RFCs coming out soon.  Most of the issues concern
key management and certificates; RFCs 1113 and 1115 are fairly stable, as is
*most* of RFC 1114.

Other useful draft RFCs are around for the digest algorithms (MD2, MD4, MD5)
and for notarization/co-certification services.  The drafts are available
from the usual places via FTP (I have no idea where since I have to use UUCP
via uunet).  

There was a brief flurry of news concerning PGP in this newsgroup a month or
so ago.  The last I heard RSA had said they would work out some kind of
licensing agreement for it, but that was right after PGP was pulled off the
net.

PGP is on the net at uwasa.  Isn't it?

Yes, the binaries are there, .... but I still want a copy of the sources.
Timo says they aren't there (perhaps he was told to remove them).

The "uwasa" referred to is "garbo.uwasa.fi" at 128.214.87.1.

Here are a few other sites where PGP can be obtained.  Given the
history of suppression of pretty good privacy, I suggest that both
getting a copy now if you will ever want one, and putting it up for FTP
yourself, are both good ideas.  Particularly if you are outside the
reach of U.S. patent laws.

			        About USENET

USENET (Users’ Network) was a bulletin board shared among many computer
systems around the world. USENET was a logical network, sitting on top
of several physical networks, among them UUCP, BLICN, BERKNET, X.25, and
the ARPANET. Sites on USENET included many universities, private companies
and research organizations. See USENET Archives.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO vs IBM.
