Mike,
According to this post by your pal Paul Engel you may want to hold off on the INTC puts til next year:

MB,

"If you can figure it out, then you know it's no good"

Au contraire, mon frere. For most of us, if the algorithm
and mode of operation are public knowledge, that makes it
more secure. It will be an
inviting target for cryptanalysts, many (though perhaps not
the majority!) of whom will happily publish their breaks for
the glory and professional prestige of having broken the thing
(or on principle). If an algorithm has been public for a long
time, especially if it is as widely used as is RSA, and no breaks
have been published you can
bet that a lot of smart people have spent a lot of effort trying
to break it, and failed. (You can also bet that a lot of smart
people who work for the NSA and the equivalents in
other countries have tried to break it, and you are unlikely to
ever know if they have failed or succeeded, but that's life.)

The algorithm should still be good if you keep your key secret.
If it's important to keep details of a cryptographic system,
not just the keys, secret in order that it be secure, then it
probably sucks.

The exception might be the presumably secret algorithms employed
by major governments. Presumably those are "public" enough within
the agency that a large number of the world's best cryptographers
spend a lot of time trying to crack them; presumably that's one
thing these agencies spend a lot of their money on. So the
total person-hours of top cryptanalytic effort expended on them
is probably high enough that they can be considered more secure
than the publicly available schemes. But they usually ain't for sale,
and you don't wanna buy them even if they are -G-. The major
reason these guys don't make the details public is probably not
so much that it jeopardizes their security, but that it makes
them available to adversaries (and in many cases, would probably
reveals new cryptographic techniques unknown in public academic
crypto circles). Of course, this is all PURE SPECULATION on my
part.

Using crypto from a private company that won't release details of
the algorithm, and preferably the source code if it's software
crypto, or the wiring diagram if it's hardware, is extremely
risky: these bozos, or maybe they're certifiable geniuses,
think it's safe, but you have no idea
what it is, so you are quite right that you will never know
if it's great stuff. The fact that it's not exposed to much
cryptanalysis, however, makes it much less likely to be any good.
(So even if they are geniuses, the people who wrote it
are bozos if they trust it, too.)

But perhaps, as an old MI spy, you have reasons for disagreeing
that you'd care to share with us -G-.

Disclaimer: I'm not an expert on this. In fact, I know nothink.

I think the main RSA patent runs out in 2000; but the fact that
their version has become standard in many applications is
probably more important than the patents.

With IMF funding getting a lot of flack, I guess the World Bank
may be worried about its funding/reputation as well, during the
Asian crisis. Now when the IMF starts underwriting NPR, things
will have really gone wacky.

Cheers,

HB
