CAM NSA Hagelin
Electronic message setter · 1951
- this page is a stub
WARLOCK I, also known as AFSAF-D79 or CXNK, and WARLOCK II, also known
as AFSAF-D80 or CXPB, were two versions of an electronic
cryptanalytic machine,
or message setter, capable of high speed decryption and
statistical recognition of plain text roughness [1]. The device was built
by Engineering Research Associates
(ERA, later: Reminton Rand) in St. Paul (Minesota, US).
There were two versions:
|
- for handling Hagelin C-38 traffic
- for wired rotor machines
|
Also known as AFSAF-D79 or CXNK, this device was made especially for solving
Hagelin C-38 and equivalent cipher machines. It has a 4-bit weighting matrix,
or weight shifter, a statistical evaluation unit and an accumulator. The output
is delivered to an CXCO regeneration typewriter.
When a hit is encountered, the windows settings are printed [1].
Development of WARLOCK started in 1947 and took four years,
with a total cost of US$ 500,000. It was so big that it could not be placed
at AFSA/NSA headquarters.
Instead it was left at the ERA factory in Minesota,
which effectively became an AFSA remote operations centre.
|
Also known as AFSAF-D80 or CXPB, this was more or less the same device as
WARLOCK I, but then universally applicable and not tailored to Hagelin machines.
It has a 3-bit weight shifter, plus five 32 x 32 matrices to simulate any
wired rotor device of which the wiring and the stepping pattern is known.
The span is 80 characters, which can be divided into two sets of 40 each [1].
