Lorenz cipher 'Rectangling' and Belief Propagation

Investigation and experiments into the connection between:

  • 'Rectangling', part of the cryptanalysis performed by the Bletchley Park codebreakers on the Lorenz cipher, and
  • Belief Propagation decoding of LDPC error-correcting codes.

See the write-up for details.
