?? Did you mean 3 rather than 8?
If this is via a non-nmr system (eg rydberg states of atoms, etc) then
this is much more impressive. The current year old best for nmr is 7
bits. Note, calling this a quantum processor is
a bit like calling an abacus a CPU.

Parameters of this form should be harmless (just like safe primes,
or Lim-Lee parameters in general -- p = 2*q_1*q_2*...*q_k + 1 where
each of the primes q_i is large, e.g. over 160 bits); then you don't
need any special checks when reusing DH keys. However, for general
DSA-style parameters, you'd have to check not only that the order
of each transmitted element is large, but that it is exactly q.
It's the smooth part of p-1 that can be exploited for attacks.
When using DSA parameters, then checking that the order of an element
is 1 or q can be done by computing the (p-1)/q-th power of that
element and verifying that you obtain 1. But that's a 864-bit
exponentiation (for 1024-bit p and 160-bit q), so it's faster
to generate a fresh DH key for these parameters -- this requires
just a 160-bit exponentiation.
So if you use DSA-style DH parameters because these are fast to
generate, then you should not resue DH keys. If you are more patient
during DH parameter generation, then you can create parameters where
key reuse is not that much of a problem (in any case, it limits
forward secrecy [you cannot reuse the key unless you store it] --
but then, so does the SSL/TLS session cache).

Also, there is some chance that the enemies will see that the
systems are secure, and stop wasting the time of their smartest
guys on it, thereby freeing them up to do others that might be
disadvantageous from the NSA's point of view.

: - a bitmap which defines which DIs hold the data for this key
:
: The 3 check numbers (check1..check3) are multiples of 3 numbers

:
: When decrypting according to a key (k), the system will attempt to decrypt

: from the lowest numbered DI upwards), so it can decrypt them with the key
: and reproduce the data file,
The check number mechanism seems slightly cumbersome. It would be more
straightforward just to put a fixed value there. Some people will whine
about known plaintext, but let's get serious: known plaintext is not
a problem with a strong cipher. The cheapest way to break this kind of
system is by torturing the key holder, not by looking for known plaintext.
No significant security weakness would arise by using a fixed check
number to recognize proper decryption.
The system can hold only a fixed number of separate files, 30 in this
case. I thought you might have something more elegant in mind that could
handle an unlimited number of files. You didn't say anything about this
limit in your earlier description.
There is a limit of 50 DIs, and the header file says that DI size is 1K.
Does this mean that you have a limit of 50K of data stored? This would
also seem to be an unfortunate limitation.
One possible weakness would arise if the attacker, by examining your
disk, found earlier deleted copies of the ciphertext file. Looking at
differences between those copies and the current one, they could see which
segments had been updated, and demand that you produce the key for those
parts. This would defeat your goal of producing only unimportant keys.
Over time, with repeated updates, DI leaks will occur. When you put a
file in, and then update it with a shorter file, the DI's allocated to
the longer version will be lost and never be usable again. This may be
a bug or a feature, depending on how you look at it.

When I initially thought about it, it seemed to me that the
individual Carnivore systems could be "prestocked" with several
thousands of pre-calculated private/public key pairs. Recognizing
public keys transmitted on the line might be troublesome, but
swapping them, once recognized, for keys from the internal list
would be a very trivial task (*IF* Carnivore systems have the
potential for such swapping; that is not yet clear to me. Elleron
says it would be feasible, but doesn't explain how).
After that point, recognizing an exchange of public-key-encrypted
session keys and replacing them with (again, precalculated) session
keys encrypted by the adversary's key would be a similar ordeal --
the harder half of the problem would be recognizing the exchange,
not replacing the user's exchange with an adversary's exchange.
At first I thought that a central repository of keys would be
necessary for the various Carnivore nodes to synchronize (ie, know
what's a user's key, and what is a Carnivore-swapped key), but just
now I realized that as long as the keys are going to be precalculated
anyway, there's no reason each Carnivore system couldn't start its
life with a complete database of all Carnivore keys, with a narrow
slice of them dedicated to its own use (only this slice would need
to have private key parts or precalculated session keys, so a
globally coherent database of public key parts would only eat about
a gigabyte per few *million* keys). I'm trying to think of another
reason that Carnivore might need to send or receive data off-site,
but I can't think of one right now.

It is my understanding that the Man-in-the-Middle attack works
independently of the strength of the keys involved, but I might
be missing something. How do you mean that it depends upon the
strength of the crypto used, and why couldn't the key-swapping be
done in real time?

It's probably more of a question of "need to know." I mean, you can

Not "instead of", but "in addition to". Every indication is that the
NSA can design ciphers very well, and that the ciphers they design
have almost _exactly_ the strength they're designed to.
However, assume even the best case: you've obtained (somehow or
other) a dozen or so chips containing a secret encryption algorithm.
It might easily take a year and a million dollars JUST to figure out
exactly what the algorithm IS. In addition, much of the time and
effort involved requires people with almost entirely different skills
than cryptanalysis.
These two factors are likely to filter out any but the very most
serious attackers from even making an attempt. Even in those cases,
the secrecy adds substantial time and effort to the job.

Unfortunately I need to correct one of the statements I made in this thread,
apparently I'm not supposed to refer to the camouflage as encryption
(although my standard definition applies*), so the actual obfuscation of the
key is performed as:

IOW, they get security by mixing operations from different groups, a

Total freedom of private speech, maybe. Public speech with anonymity,

You don't say what ciphers you want, etc., but simplest is probably
use the conventional encryption libraries from OpenSSL

Mexico Race Hinges on Code Crack by Mike Kamber
3:00 a.m. Jun. 30, 2000 PDT
MEXICO CITY -- Just days before an election that threatens to end the 71-year
rule of Mexico's Revolutionary Institutional Party (PRI) computer hackers and
encrypted CD-ROMs have become key factors in Sunday's ballot.
Many here believe the CD-ROMS will reveal a tangled web of alleged election
fraud, drug trafficking, and most importantly, corruption tied to the lending
practices of Mexico's banks in the early 1990s.
Billions of dollars went to corporations and wealthy individuals supporting
the PRI, which obtained millions in direct loans to finance its 1994 political
campaign.
But later that year, inflation rose and the defaults began.
The PRI-dominated congress created a fund to help Mexico's banks weather this
"small financial crisis." The fund assumed repayments only on the largest
loans, those owed by corporations, leaving smaller debtors accountable in full.
Fobaproa, as the scandal came to be known, today amounts to a US$4.5 billion
dent in Mexico's budget. Critics have missed no opportunity to remind voters
that 2.5 million Mexicans working full time at the country's $3.50-a-day
minimum wage would take 35 years to repay the Fobaproa debt.
Thus, it is no wonder the CD-ROMs now referred to by one and all as "the
famous CDs" and their elusive contents are the stuff of speculation because
many Mexicans don't believe the PRI -- the only party that has ever ruled their
country -- will give up power easily.
The Revolutionary Democratic Party (PRD), running a distant third in the polls
despite the efforts of its candidate, Cuauhtemoc Cardenas, had little to lose
when it hired hackers to crack the encryption.
It was a calculated decision. Many Mexicans live on as little as $30-a-month
in villages without electricity. If the PRD can de-encrypt the CD-ROMs and
implicate rival politicians before the election, Cardenas and his party are
convinced the resentment of poor voters could change the course of Mexican
political history.
Opening the encrypted CD-ROMs requires six passwords. There is one for each of
Mexico's five political parties and a sixth that belongs to a Canadian auditor,
Michael Mackey, hired by Mexico's congress to conduct an external audit of the
bailout. Mackey's results, encrypted passwords and all, are on the famous CDs.
According to Delores Padierna, a PRD politician involved in the hacking
effort, the PRI also has Mackey's audit results on an unencrypted disk. But the
PRD doesn't, and as of now, the hackers, dubbed "technicians" by the party,
have cracked all but the PRI password in a high stakes race to the polls.
At PRD headquarters, Hilario Juarez Trejo, the party's computer coordinator,
is at once knowledgeable and cagey when asked about the party's efforts.
"The one we don't have contains 11 characters -- eight letters and three
numbers," he said. "So there are millions of combinations -- it could take time
to find it."
And as the election draws nearer, Padierna worries more.
"We know that they are opening the unencrypted CD-ROMs all the time," says
Padierna. "Not only are they reviewing them, but they are modifying and
deleting data."
Her fear is that newly modified data will be burned onto a CD and presented by
the PRI as original, making the hackers' efforts that much more important for
Mexico's future.
"Publishing the contents of the CDs could change the outcome of the
elections," says PRD Congressman Ramirez Cuellar, "because (Francisco
Labastida), the presidential candidate of the PRI, would be implicated."
Now, the PRI is threatening legal action if the PRD goes public with the
contents of the CD-ROMs, claiming that would violate the lenders' fiduciary
responsibilities.
Ramirez Cuellar laughs at the thought. "Fobaproa is the robbery of the
century, maybe the biggest in Mexican history," he said. "The banker's secrets
are the secrets of delinquents."

Given that every ISP has to be connected through some point-to-point broadband
link (Are there still any ISPs using dialup ISDN?), the Carnivore box wouldn't
have to be on the ISP's premises. Just stick it on the other end of the link,
and prohibit the broadband carrier from telling the ISP owner that he's being
monitored.
This sounds like a trivial variation on the proposal to equip all telephone
central offices with hardware that would allow the FBI to monitor any telephone
line by remote control. AFAIK, that one is already in progress, if not
complete.
Of course, these devices would be activated on a particular line only with a
court order. Our government would no more conduct a nationwide,
unconstitutional snooping operation than it would inject unsuspecting hospital
patients with plutonium salts, or allow war criminals to get away with their
crimes in exchange for their data.
