History of cryptography - Shannon.
The era of modern cryptography really begins with Claude Shannon, arguably the father of mathematical cryptography. In 1949 he published the paper Communication Theory of Secrecy Systems in the Bell System Technical Journal and a little later the book, Mathematical Theory of Communication, with Warren Weaver. These, in addition to his other works on information and communication theory established a solid theoretical basis for cryptography and for cryptanalysis. And with that, c ...

| | | | History of cryptography - An encryption standard: Encyclopedia II - History of cryptography - World War II cryptography By World War II, mechanical and electromechanical cipher machines were in wide use, although — where such machines were impractical — manual systems continued in use. Great advances were made in cipher-breaking, all in secrecy. Information about this period has begun to be declassified as the official British 50-year secrecy period has come to an end, as U.S. archives have slowly opened, and as assorted memoirs and articles have appeared.
The Germans made heavy use, in several variants, of an electromechanical rotor machine known ...

| | | | History of cryptography - An encryption standard: Encyclopedia II - History of cryptography - Cryptography from 1800 to World War II Although cryptography has a long and complex history, it wasn't until the 19th century that it developed anything more than ad hoc approaches to either encryption or cryptanalysis (the science of finding weaknesses in crypto systems). Examples of the latter include Charles Babbage's Crimean War era work on mathematical cryptanalysis of polyalphabetic ciphers, rediscovered and published somewhat later by the Prussian Friedrich Kasiski. Understanding of cryptography at this time typically consisted of hard-won rules of thumb; see, for example, ...

| | | | History of cryptography - An encryption standard: Encyclopedia II - History of cryptography - Medieval cryptography It was probably religiously motivated textual analysis of the Qur'an which led to the invention of the frequency analysis technique for breaking monoalphabetic substitution ciphers sometime around 1000 CE. It was the most fundamental cryptanalytic advance until WWII. Essentially all ciphers remained vulnerable to this cryptanalytic technique until the invention of the polyalphabetic cipher by Alberti (ca 1465), and many remained so thereafter.
Cryptography became (secretly) still more important as a consequence of political competitio ...

| | | | History of cryptography - An encryption standard: Encyclopedia II - History of cryptography - Classical cryptography The earliest known use of cryptography is found in non-standard hieroglyphs carved into monuments from Egypt's Old Kingdom (ca 4500+ years ago). These are not thought to be serious attempts at secret communications, however, but rather to have been attempts at mystery, intrigue, or even amusement for literate onlookers. These are examples of still other uses of cryptography, or of something that looks (impressively if misleadingly) like it. Later, Hebrew scholars made use of simple monoalphabetic substitution ciphers (such as the Atbash ciph ...
