Title:
Quagmire ciphers and group theory: Recovering keywords from the key table

Authors: Thomas Kaeding

Abstract:

We demonstrate that with some ideas from group theory we are very often able to recover the keywords for a quagmire cipher from its key table. This would be the last task for a cryptologist in analyzing such a cipher.
