The Chaocipher Clearing House
Progress Report #17
Chaocipher Revealed: The algorithm is publicly explained for the first timeThis is it: we've reached the endgame.
years after its invention, and fifty-seven years after challenge messages were published,
John F. Byrne's Chaocipher algorithm can finally be revealed.
The cryptologic community can now examine this tantalizing
cipher, which eluded solution all these years, only this time with the knowledge of
how it works.
The story of how and why Chaocipher came to be
revealed can be read in Progress Report #16. With no further ado,
you can now read the document entitled "Chaocipher Revealed: The Algorithm".
the next few days we hope to upload papers detailing how the exhibits
in Byrne's autobiographical "Silent Years" were enciphered. These
will hopefully be followed by papers by other researchers on such
topics as assessing the Chaocipher's cryptographic security,
cryptanalysis of Chaocipher messages, the mechanical description of
Chaocipher, Byrne's proposed key distribution method, and more.
Chaocipher Clearning House invites all students of cryptography to
submit Chaocipher-related papers for inclusion on this web site.
