X-WR-CALDESC:19 June 1963: US and USSR agreed to a 'hotline' between Moscow
and Washington. It was a one-time tape/teletype system for which the Sovi
ets and Americans exchanged compatible equipment. The original hotline wen
t into use as a result of the Cuban Missile Crisis\, a few months before t
he assassination of President John F. Kennedy. It was phased out in the ea
rly 1980s and replaced by a computerized system. The encryption system\, E
CTRRM\, was attached to the teletype and donated to the National Cryptolog
ic Museum by Norway. A Norwegian company manufactured the system used by b
oth ends of the Washington-Moscow link. It used a 5-hole punched paper tap
e for its keying system. Notice the stamp on the side of the paper roll. I
f unrolled for nefarious purposes\, the paper could not be rolled back wit
h exactly the same tension and the stamp will be distorted. This simple te
chnique provided a high level of security. \n\nJohn F. Kennedy became the
first U.S. president to have a direct line to the Kremlin in Moscow. The “
hotline” was designed to facilitate communication between the president an
d Soviet premier. However\, though the public perception of a 'Red Phone'
that went directly to Moscow is not exactly how the process worked. The 'h
otline' would first involve a call to the Pentagon where the message would
be typed into a teletype machine\, encoded\, and then transmitted. The me
ssage would reach Moscow within minutes. Read the excerpt below to learn m
ore.\n\nExcerpted from History.gov:\n\n'An article in The New York Time
s described how the new system would work: Kennedy would relay a messa
ge to the Pentagon via phone\, which would be immediately typed into a tel
etype machine by operators at the Pentagon\, encrypted and fed into a tran
smitter. The message could reach the Kremlin within minutes\, as opposed t
o hours. Although a far cry from the instantaneous communication made poss
ible by today’s cell phones and email\, the technology implemented in 1963
was considered revolutionary and much more reliable and less prone to int
erception than a regular trans-Atlantic phone call\, which had to be bounc
ed between several countries before it reached the Kremlin.\n\nIn 1967\, P
