Abstract
Two Second World War research papers by Alan Turing were declassified
recently. The papers, The Applications of Probability to Cryptography and its
shorter companion Statistics of Repetitions, are available from from the
National Archives in the UK at www.nationalarchives.gov.uk. The released papers
give the full text, along with figures and tables, and provide a fascinating
insight into the preparation of the manuscripts, as well as the style of
writing at a time when typographical errors were corrected by hand, and
mathematical expression handwritten into spaces left in the text. Working with
the papers in their original format provides some challenges, so they have been
typeset for easier reading and access. We recommend that the typeset versions
are read with a copy of the original manuscript at hand. This document contains
the text and figures The Applications of Probability to Cryptography, the
companion paper is also available in typeset form from arXiv at www.arxiv.org.
These notes apply to both documents.
