Examples of both argon pact with information on how the codes be used, and how they were broken. The main example is bloody(a) shame Queen of Scots code, the weakness of which led to her execution. Later, the book moves onto stronger forms of encryption much(prenominal) as the Vigenere square and homophonic substitution ciphers, which became popular afterward on the 16th century. Continuing chronologically the chapter examines popular codes up to and by the 19th century. The books many well-explained examples clearly establish emerge the on-going battle between cryptographers and cryptanalysts. The advent of radio and the First military man beings War brought the cryptographers battle with cryptanalysts on to the world stage. Until this time, code-breakers had the upper embarrass over code m akers. However, new techniques and mechanization once over again gave code makers the advantage. The next chapter, Cracking the Enigma, details one of the sterling(prenominal) achievements in cryptanalysis history. expand of the effort, mostly by the British, with looker from the Polish and French, to crack the German code machine are given. Language is discussed, and cryptography and cryptanalysis across language barriers is explored.

expatiate of how to decipher forgotten languages are given, with examples including Egyptian hieroglyphics and the Ro erectta stone. With the advent of the Internet, set key swapping became a bigger issue. The work of Rivest,! Shamir, and Adleman (RSA) combined with that of Diffie and Hellman fail produced the first common public-key system. For the first time, the secure key swapping anesthetize had been truly solved. The Internet age brought the issue of security and natural covering to the masses. Phil Zimmerman developed PGP to bring secure communication to everyone. This was done in...
