More on the Unabomber’s Code
Last month I posted about Ted Kaczynski's pencil-and-paper cryptography. It seems that he invented his own cipher, which the police couldn't crack until they found a description of the code amongst his personal papers.
The link I found was from KPIX, a CBS affiliate in the Los Angeles area. Some time after writing it, I was contacted by the station and asked to comment on some other pieces of the Unabomber's cryptography for a future story (video online).
There were five new pages of Unabomber evidence that I talked about (1, 2, 3, 4, and 5). All five pages were presented to me as being pages written by the Unabomber, but it seems pretty obvious to me that pages 4 and 5, rather than being Kaczynski's own key, are notes written by a cryptanalyst trying to break the Unabomber's code.
In any case, it's all fascinating.
