As I understand the story Mr Carrion is telling, the Soviets were encrypting all their communications from the US using one-time pads. However up to the mid 1940s, some of these one-time pads were re-used, which allows a cryptanalyst an entry into breaking the ciphers. This practice stopped by the mid 1940s, but by then enough traffic had been accumulated for a team of analysts to spend the best part of four decades trying to decipher it. The fact that it took nearly forty years - plus the fact that, apparently, less than twenty percent of the traffic was ultimately deciphered - shows just how extremely difficult it can be to break a one-time cipher, even when you have a crib. And this is where the story seems to break down. If it's true that, after the mid 1940s, the Soviets were using one-time pads and weren't re-using them, then these ciphers could not have been broken using a known plaintext attack. So "gardening" would have been completely useless. So for Mr Carrion's story to make any sense at all, the cipher which constituted the target for this "gardening" approach must have been something else. And it's not clear to me what it was, assuming it existed. Cathy Listen to 'Strange Days...
