During World War II, the small group of mathematicians, cryptographers and codebreakers at Bletchley Park in England successfully decoded the Enigma Machine, a German-designed cipher machine used to encrypt radio transmissions. This immense breakthrough allowed the British to decipher and know every German movement for the remainder of the war.
The greatest problem with this was that, even though the English knew every German move, they couldn't act on most of it. This was because if the Germans realized their cipher were broken, they would change how they would encrypt their future messages, and the years spent decoding the Enigma machine would be for naught, and a newer method to encrypt might prove impossible to break. They could only act on the most strategically important information.
As a result of inaction, many innocent people perished and avoidable incidents resulted in death. But because the Germans never knew their machine was decrypted, the Eastern Front and Normandy became paramount successes.
We are seeing this today.
It's not that nothing is happening, but that nothing CAN happen without the enemy detection. They must not be aware of how much control and information we possess, and how much surveillance we conduct against them.
But there will be time when we show hand.
And it will be glorious.
This is excellent a mid 90’s documentary of over three hours produced by uk channel 4 that I highly recommend, go’s on to the development of the Alan Turings Bombe the 1st algorithmic search engine and development of ‘collosus’ the worlds 1st programable computer that read German cipher traffic in the matter of minutes.
