On the 32-Character Zodiac Cipher [PDF]
, 2023 A possible new approach to the Zodiac Killer\u27s 32-Character Cipher (Z32) is proposed based on the strengths and weaknesses of previous approaches and novel interpretations.

U ovom radu prikazan je sadržaj i povijesni kontekst Zodijakovih šifri, Z408, Z340, Z13 i Z32, te je detaljno opisan postupak dešifriranja istih. Spomenute šifre svojom su složenošću desetljećima zbunjivale stručnjake iz područja kriptografije, forenzike

The Zodiac Killer’s Z13 (“My name is—”) and Z32 (map/bomb code) ciphers remain unsolved despite decades of analysis. This paper proposes that they are not conventional homophonic substitution puzzles, but instead form a deliberately constructed self-closing disclosure system encoding permanent structural ambiguity rather than recoverable plaintext ...

Geospatial Constraint Satisfaction in the Zodiac Z32 Cipher
The Z32 cipher, a 32-character homophonic substitution cipher sent by the Zodiac killer on June 26, 1970, has resisted cryptanalysis for over 55 years. With only 29 unique symbols in 32 positions, Z32 falls below the unicity distance required for linguistic frequency analysis-the method that solved the Zodiac's longer ciphers Z408 and Z340.

The Zodiac Z32 Cipher as a Formally Underdetermined Instruction System
This paper analyzes the Zodiac Killer’s Z32 cipher using a formal constraint and degrees-of-freedom framework. Rather than attempting a literal decoding, it defines solvability operationally and evaluates whether Z32 contains sufficient constraints to uniquely determine a physical location, geometric construction, or finite terminating procedure.

The Zodiac Z32 Cipher as a Structural Anti-Cipher: A Constraint-Based and Algebraic Analysis
The Zodiac Killer’s 32-symbol cipher (Z32) has long been treated as an unsolved or poorly executed cryptographic message, most often hypothesized to encode geographic coordinates or navigational instructions anchored at Mount Diablo. Despite decades of attempted solutions, no decoding has yielded a stable, reproducible result.

The 32-character ciphertext ("Z32") mailed by the Zodiac Killer in June 1970 has historically been resistant to standard cryptanalysis due to its low unicity distance. This paper presents a solution derived by reframing the cipher as a Geographic Constraint Satisfaction Problem (GCSP).
