Britain's code-breakers acknowledged Friday that an encrypted handwritten message from World War II, found on the leg of a long-dead carrier pigeon in a household chimney in southern England, has thwarted all their efforts to decode it since it was sent to them last month.
This is a website introducing codes and ciphers in WW II by Tony Sale. Given this specific war context, is there really a guideline of what an action is ethical and what is not in terms of cryptoanalysis? Would an action be ethical whenever the majority's well-being is satisfied, or there's a line that should not be crossed?
"The remains of a World War Two carrier pigeon which was lost in action 70 years ago while delivering a top secret message over enemy lines has been found in a chimney in Bletchingley, Surrey.
The skeleton of the bird has a small red cylinder attached to its foot which contains a mysterious cigarette paper sized coded message. The message is deemed so sensitive, that Codebreakers at GCHQ in Cheltenham are now frantically trying to decipher it."
The "uncrackable codes" made by exploiting the branch of physics called quantum mechanics no longer require the use of special "dark fibres" and have been sent down kilometres of standard broadband fibre.
"Around sixty Bletchley Park veterans gathered again at the Home of the Codebreakers on Sunday 2nd September, for the annual Enigma Reunion.
The event is timed each year to coincide with the anniversary of the arrival of the first codebreakers at Bletchley Park, after they received the coded message 'Auntie Flo is not so well', indicating they should report for top secret duties."
