The Solution of the Zodiac Killer's 340-Character Cipher
David Oranchak, Sam Blake, Jarl Van Eycke, 2024.
The solvers' account of how the Zodiac killer's 340-character cipher was broken in 2020; the cipher combined homophonic substitution with a transposition.
What it's used for here
The book models its annealing solver on this solution, borrows its periodic bigram-repeat diagnostic for transposition, and cites the cycling of homophones in the Zodiac's 408-symbol cipher.
