Claude Shannon. Claude E. Shannon is considered by many to be the father of mathematical cryptography. Shannon worked for several years at Bell Labs, and during his time there, he produced an article entitled "A mathematical theory of cryptography"..
What is the history of cryptography?
The first known evidence of the use of cryptography (in some form) was found in an inscription carved around 1900 BC, in the main chamber of the tomb of the nobleman Khnumhotep II, in Egypt. The scribe used some unusual hieroglyphic symbols here and there in place of more ordinary ones..
What was the first cryptography book written?
Johannes Trithemius' Polygraphiae (1518) is the first printed book on cryptology..
Who is the author of cryptography?

Who wrote the first cryptography book?
Johannes Trithemius' Polygraphiae (1518) is the first printed book on cryptology. In contrast, the revolutions in cryptography and secure communications since the 1970s are well covered in the available literature..

History of cryptography books
Fish was the UK's GC&CS Bletchley Park codename for any of several German teleprinter stream ciphers used during World War II. Enciphered teleprinter traffic was used between German High Command and Army Group commanders in the field, so its intelligence value (Ultra) was of the highest strategic value to the Allies. This traffic normally passed over landlines, but as German forces extended their geographic reach beyond western Europe, they had to resort to wireless transmission.

Cryptographic device
In cryptography, a pinwheel was a device for producing a short pseudorandom sequence of bits, as a component in a cipher machine. A pinwheel consisted of a rotating wheel with a certain number of positions on its periphery. Each position had a pin, cam or lug which could be either set or unset. As the wheel rotated, each of these pins would in turn affect other parts of the machine, producing a series of on or off pulses which would repeat after one full rotation of the wheel. If the machine contained more than one wheel, usually their periods would be relatively prime to maximize the combined period. Pinwheels might be turned through a purely mechanical action or electromechanically.
