>There's also a part on how the secret on Enigma's breaking has been kept for decades after the war, supposedly because Enigma machines had been distributed to British colonies (and ex-colonies) and British intelligence wanted to be able to decrypt their communication.
Not to mention any units captured by the Soviets - GCHQ wanted to make sure any use of the units by them would be decryptable as well.
- qubex 8y agoGCHQ and it’s American counterparts were more interested in deceiving the Soviets into believing that they hadn’t been able to break a type of cipher unrelated to Enigma, namely the pseudo-Vernam Ciphers as embodied by Tunny/Lorenz/* Geheimschreiber* for transmitting stream-enciphered teleprinter traffic (as decoded by Colossus). Enigma was trivial by comparison and it’s insecurity was known to the USSR.
