- Rockex, or Telekrypton, was an offline one-time tape Vernam cipher machine known to have been used by Britain and Canada from 1943. It was developed by Canadian electrical engineer Benjamin deForest Bayly, working during the war for British Security Coordination. "Rockex" was named after the Rockefeller Center, together with the tradition for naming British cipher equipment with the suffix "-ex" (e.g. Typex). In 1944 an improved Rockex II first appeared. 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. After WW2 the Rockex machines and the code tapes were manufactured in great secrecy under the control of the Secret Intelligence Service (SIS), also known as MI6, at a small factory at Number 4 Chester Road, Borehamwood on the northern outskirts of London. To minimise the number of people who knew about the process, MI6's head of communications, Brigadier Sir Richard Gambier-Parry, took out a personal lease on the factory buildings and employed people through the local labour exchange as an entirely private venture ostensibly unconnected with government. The end product was then sold to the government departments who used the machines. This was not discovered by the UK Treasury until 1951 who were most concerned that no form of financial auditing had ever been exercised over the organisation. The Treasury officials were eventually convinced that the factory needed to be treated as a special case and they allowed it to continue privately but with a special arrangement for top secret auditing (Natl Archives file T220/1444) (en)
- ROCKEX era una macchina crittografica OTT basata su valvole prodotta negli Stati Uniti a partire dal 1940 in poi dall'esperto di comunicazioni canadese Benjamin Deforest Bayly su richiesta della British Intelligence. La macchina entrò in servizio nel 1943 e successivamente ebbe altre versioni migliorate come i modelli BID / 08/05, BID / 08/06, BID / 08/07 ecc. Finché la produzione di esse non venne dismessa nel 1983. La macchina si basa sulla TeleKrypton che è stata modificata e trasformata in una macchina crittografica OTT, ROCKEX veniva usata per trasmettere messaggi tra Camp-X e Whitby-2 in Canada, furono prodotte 12 macchine di questo tipo prima dell'uscita del secondo modello, successivamente la NATO ha preso in considerazione la ROCKEX per la trasmissione di messaggi.
