The only encryption used by the USA
(and Canada as well as the UK) was the "Sigaba" as shown
on the USS Pampanito floating museum and at the NSA
on-line Museum.

Wrong, kind elderly Gentleman. It wasn't the "only encryption used by
the USA".

SIGABA (KL-29/BACCUS) was only ONE of SEVERAL encryption systems used
by the USA
during WWII. In fact, it wasn't even the most commonly used one
(KL7/ADONIS
holds that honor).

Of course it's "wrong," you are always "right." :-)

Never had a crypto clearance in the service, certainly
not in WW2. You have one then? [of course you did...]

Have to "dot the i and cross the t" to the EXACT
number or else be sentenced to a capital-crime
felony in here? :-)

All I know is the basic principle of the system,
obtained in a couple of interesting books by
CIVILIANS! :-) Also an article by the Chief
Cryptographer of the U.S. Army...a civilian! :-)


The "Sigaba" system (TTY), upgraded to post-WW2 standards
was severely compromised by the capture of the USS Pueblo
off the North Korean coast in 1968.

Wrong again, SIGANDERSON. SIGABA (and it's "upgrades") were retired
from
service in 1959, almost a decade before the Lloyd Bucher shamefully
struck his
colors to the Koreans..

No problem, Super Chief. :-)

Until around 1964 I didn't KNOW the EXACTNESS of
the systems or even how it was done. The crypto
stuff would roll in looking for all the world as
way-off-bias-distortion-prone TTY on any standard
TTY...on what I saw in the Army.

I'm sure you think that the Army sent everything
"in clear" using morse code (to confuse the 'enemy')
and all that. That's another subject of course and
I'm not allowed to talk of that; I need an AMATEUR
RADIO license in order to talk about military/all-
Navy encryption. :-)

The system used then was a "rotor" type (familiar
name). Essentially a set of rotary switches turning
at different rates (according to key settings, crypto
key, not key on a manual keyboard operation). Those
rotary switches ("rotors") scrambled the normal TTY
in synchronism with the TTY motor and would also
UN-scramble received TTY. Neat thing about that,
even with the "wrong" name and all the EXACT number
and letter designators, was that NOBODY COMPROMISED
IT! Sunnuvagun!

Lots and lots of cryptologists and historians have
tried to see if anyone compromised it on any intercepts
during WW2 and somewhat afterwards (I won't say the
EXACT year because you want to snarl and argue about
it if I do) but haven't come up with anything yet.

Of course you are on this wonderful, traditional,
"do or die," "death before dishonor" bull**** attitude
in regards to Commander Bucher. Riiiiight...the USN
thoughtfully "armed" the USS Pueble with a single
machine gun and a few personal arms of some of the
personnel. NOT ENOUGH destruct flares on board to
destroy equipment. Pueblo was surrounded in shallow
water...not a big problem to have NORTH Korean divers
raise enough equipment to sell to the USSR. But...
"being there" (in your heart) you would want everyone
to FIGHT TO THE LAST MAN! Wow, lot of "good" that was
goint to do.

By the way, since you are so picky-picky about EXACT
names and things, the USS Pueblo was captured by
NORTH Koreans. Korea isn't unifed yet, hasn't been
since the USSR jumped in on the tailboard of WW2 and
"occupied" the North and sticking in their communist
government ideas there. As a separate Korean nation,
that is.

The crew of the USS Pueblo (officially a USN ship,
an "oceanographic research vessel" according to our
government) pretty much survived captivity. [do
you need an EXACT body count?] Bucher survived.
But, Bucher died not too long ago. No problem for
you, huh? The USN didn't haul him up for any courts
martial. He was allowed to retire. [you were allowed
to retire, right?]

CWO Walker, USN, STOLE whole technical manuals (by
photographic copying) and Key Lists while SERVING in
the USN. Sold the material to the USSR. Walker was
eventually caught, tried, and sentenced to life in a
federal pen. [do you need the EXACT details on that,
too, and if no one supplies them, are they "all
wrong?"] Walker is STILL ALIVE! Sunnuvagun!

You don't posit that as a "terrible thing," do you?
You want to try and convict (in absentia) a USN
commissioned officer stuck in an untenable position
in his command...but you don't give a **** about
ANOTHER USN officer, a Warrant, doing deliberate
TREASON while SERVING! That's okay?

Master Chief Radioman, US Navy

Good grief, you didn't "cross the tee" in your
manuevers properly. You should have pointed out
that the USN closed down ELF transmitters in Clam
Lake, WI, and Republic, MI, at the end of September
2004!!! No more 76 Hz at 1 MW. [too many in the
U.S. north country want to "save the environment"
and "preserve world peace" by withholding the use
of *nuclear* (horrors!) missles] Riiiight...76 Hz
is terribly harmful to the ecology they think!

Tsk, tsk! You could have had a FINE time doing the
pillory bit on me...but you NEGLECTED to do so!

Missle submarines and attack submarines have to use
alerts from VLF stations NAA, NLK, NPM, NML, NAU,
NRK, NWC...frequencies from 19.8 to 40.8 KHz. But,
I almost hesitate to list those since you will NO
DOUBT want the EXACT details, the EXACT locations,
and the EXACT mode, protocol, and all that...or ANY
listing is TOTALLY WRONG!!! :-)

Cool it, Master super-duper Chief (USN). I'm still
a citizen of the U.S. of A. and served in MY
country's (USA) military BEFORE you did. I know
that doesn't count for much in this din of inequity
but it's all I got. :-)

By the way, for EXACTNESS, my surname was NEVER
"SIGANDERSON." You made a "mistake" but I won't
hold anything against you. Well, maybe a bayonet
or such... :-)

Temper fry...
