"Secret Alan Turing cryptanalysis papers released by GCHQ 

By Cory Doctorow at 12:17 pm Friday, Apr 20 

GCHQ, the UK government's communications headquarters, has published a set of 
code-breaking papers written by Alan Turing during WWII. The papers had been 
held in secret since they were written. The papers are c"The Applications of 
Probability to Crypt" and "Paper on the Statistics of Repetitions" and they 
deal with cryptanalysis techniques to optimize breaking Nazi ciphers. They're 
displayed at the National Archives at Kew. The BBC has more: 

According to the GCHQ mathematician, who identified himself only as Richard, 
the papers detailed using "mathematical analysis to try and determine which are 
the more likely settings so that they can be tried as quickly as possible..." 

Richard said that GCHQ had now "squeezed the juice" out of the two papers and 
was "happy for them to be released into the public domain".
