Thorough, systematic introduction to serious cryptography, especially strong in modern forms of cipher solution used by experts. Simple and advanced methods. 166 specimens to solve — with solutions.

---

Gaines's Cryptanalysis (formerly published as Elementary Cryptanalysis) is a standard elementary and intermediate text for persons seriously interested in modern science methods for enciphering and deciphering cryptograms. It does not simply repeat older material, but contains much about modern cryptanalysis that is not generally known except to experts. It is especially strong in modern forms of cipher solution.This clear and thorough text also provides the reader with 166 specimen codes to solve. This edition for the first time also includes solutions. A special appendix includes final letters, sequence charts, digram, trigram tables, most common words in English and frequencies in English, German, French, Italian, Spanish, and Portuguese.
