Rockex
From Wikipedia, the free encyclopedia
Rockex, or Telekrypton, was an offline one-time tape cipher machine known to have been used by Britain and Canada from 1943. It was developed by Benjamin deForest Bayly, working during the war for British Security Coordination.
"Rockex" was named after the Rockefeller Center[1], together with the tradition for naming British cipher equipment with the suffix "-ex" (e.g. Typex).
In 1944 an improved Rockex II first appeared[1]. There were also a Mark III and Mark V. After the war it was used by British consulates and embassies until 1973, although a few continued in use until the mid 1980s[2].
