FBI Affidavit on Ex-NSA Cryptanalyst
We offer the FBI's 23-page affidavit of charges against David
Sheldon Boone, ex-NSA cryptanalyst who allegedly
passed top secret SIGINT, EW and nuclear targeting plans
to the Soviets:
Tantalizing hints on means and methods, quoting the affidavit of the
FBI agent in charge:
On one occasion, "Igor" [Soviet agent] told BOONE that the
KGB/SVRR had access to United States Signals Directive
(USSID) Zero, which was an index of all other USSIDs, and
from this index IGOR asked BOONE to obtain specific USSIDs.
I have ascertained that USSIDs are classified NSA publications
for use in providing Signals Intelligence (SIGINT) support to
the United States military.
BOONE told the OA [FBI Operational Asset posing as Soviet
agent to set up Boone] that he had given "Igor" a photocopy
of an NSA document entitled "United States Signals Intelligence
Directive (USSID) 514," dated May 6, 1988. BOONE told the
OA that this USSID was unusual because it was one of few
USSIDs to be classified TOP SECRET rather than SECRET.
BOONE told the OA that USSID 514 was not widely
disseminated but that one copy had been at USAFS
And more on Boone's training and duties in cryptanalysis at
Fort Meade and in Germany.
Bad Ausburg is the location of one of the NSA intercept stations
for the Echelon program is it not?
