First published in 1956 as a classified text by the U.S. Government, this book discusses the analysis of unilateral, multilateral, and polygraphic systems, as well as the use of isologs, pattern-words, etc. The use of the international (Baudot) teleprinter code and the Morse code in cryptography is also covered. It is particularly thorough in its analysis of four-square, two-square, and the Playfair Cipher system. Cryptosystems employing irregular-length cipher units, monome-dinome systems, are covered in depth.
