* HAGELIN, Albert Viljam ( 1881 – 1946 ) Nasjonal Samling politician and collaborator.

* Alberti was an accomplished cryptographer by the standard of his day, and invented the first polyalphabetic cipher which is now known as the Alberti cipher and machine-assisted encryption using his Cipher Disk.

British examples are At Risk ( 2004 ), Secret Asset ( 2006 ), Illegal Action ( 2007 ), and Dead Line ( 2008 ), by Dame Stella Rimington ( formerly the Director General of MI5 from 1992 to 1996 ) and The Code Snatch ( 2001 ) by Alan Stripp, formerly a cryptographer at Bletchley Park.

The program was led by David Peck Todd with the military assistance of Admiral Edward W. Eberle ( Chief of Naval Operations ), with William F. Friedman ( chief cryptographer of the US Army ), assigned to translate any potential Martian messages.

During her flight from the Electorate of the Palatinate, Eliza becomes pregnant by Louis's cryptographer, though popular knowledge suggested it was the French nobleman Etienne D ' Arcachon's child.

Peeping Tom is a 1960 British thriller film directed by Michael Powell and written by the World War II cryptographer and polymath Leo Marks.

The M-209 was designed by Swedish cryptographer Boris Hagelin in response to a request for such a portable cipher machine, and was an improvement of an earlier machine, the C-36.

The society is principally described by Michel Lamy in his work Jules Verne, Initie et Initiateur, based on extrapolations of previous work by cryptographer Claude Sosthène Grasset d ' Orcet.

Paulo Pancatuccio was a 16th-century cryptographer born in Volterra and employed by the Pope to break enciphered documents.

The company was based on technology developed by the Israeli cryptographer Adi Shamir and his partner Amos Fiat. Shamir and Fiat devised a coding solution for the encryption system used in satellite broadcasts.

Inspired by Theosophical lore and several visiting Mongol lamas, Gleb Bokii, the chief Bolshevik cryptographer and one of the bosses of the Soviet secret police, along with his writer friend Alexander Barchenko, embarked on a quest for Shambhala, in an attempt to merge Kalachakra-tantra and ideas of Communism in the 1920s.

This signal was intercepted and broken by US Intelligence ( by cryptographer Commander Laurance Safford based in Washington ) and, naturally, a close monitoring of the Japanese daily shortwave broadcast was instituted for the codes, dubbed the Winds Code by the Americans.

In cryptography, REDOC II and REDOC III are block ciphers designed by Michael Wood ( cryptographer ) for Cryptech Inc and are optimised for use in software.

It was invented by famous French cryptographer Felix Delastelle.

Delastelle is unusual for being an amateur cryptographer at a time when significant contributions to the subject were made by professional soldiers, diplomats and academics.

After high school he largely hung out on the street corners for two years, followed by two years in the army, serving in the 101st Airborne and as a cryptographer of the 595th Signal Corp in Boblingen, Germany.

The Cambridge cryptographer Ross Anderson has great concerns that " TC can support remote censorship [...] In general, digital objects created using TC systems remain under the control of their creators, rather than under the control of the person who owns the machine on which they happen to be stored ( as at present ) [...] So someone who writes a paper that a court decides is defamatory can be compelled to censor it — and the software company that wrote the word processor could be ordered to do the deletion if she refuses.

In the words of cryptographer Bruce Schneier, " DES did more to galvanize the field of cryptanalysis than anything else.

* 1516 – Johannes Trithemius, German cryptographer ( b. 1462 )

Leon Battista Alberti ( February 18, 1404 – April 20, 1472 ) was an Italian author, artist, architect, poet, priest, linguist, philosopher, cryptographer and general Renaissance humanist polymath.

After graduating, Anderson worked for the final year of World War II as a cryptographer for the Intelligence Corps, at the Wireless Experimental Centre in Delhi.

Indeed, in 1996, cryptographer Bruce Schneier characterized an early version as being " the closest you're likely to get to military-grade encryption.

* Robert Tappan Morris ( born 1965 ), creator of the first Internet worm and son of the cryptographer Robert H. Morris

* Leon Battista Alberti ( 1404 – 1472 ) was an Italian author, artist, architect, poet, linguist, philosopher, and cryptographer, and general Renaissance humanist polymath.

* September 14 – William F. Friedman, American cryptographer ( d. 1969 )

** Blaise de Vigenère, French cryptographer, diplomat, scientist, and author ( b. 1523 )

* February 1 – Johannes Trithemius, German scholar and cryptographer ( d. 1516 )

* April 5 – Blaise de Vigenère, French diplomat and cryptographer ( d. 1596 )

Bruce Schneier (; born January 15, 1963 < ref name = fb >) is an American cryptographer, computer security specialist, and writer.

* December 13 – Johannes Trithemius, German scholar and cryptographer ( b. 1462 )

Adi Shamir (; born July 6, 1952 ) is an Israeli cryptographer.

This appears, at first glance, to be an unrealistic model ; it would certainly be unlikely that an attacker could persuade a human cryptographer to encrypt large amounts of plaintexts of the attacker's choosing.

Ronald Linn Rivest ( born 1947, Schenectady, New York ) is a cryptographer.

William Frederick Friedman ( September 24, 1891 – November 12, 1969 ) was a US Army cryptographer who ran the research division of the Army's Signals Intelligence Service ( SIS ) in the 1930s, and parts of its follow-on services into the 1950s.

He became fascinated with the work as he courted Elizebeth Smith, Mrs. Gallup's assistant and an accomplished cryptographer.

The ( Hagelin ) C-52 and CX-52 were cipher machines manufactured by Crypto AG starting 1951 / 1952.

There is some speculation that the CX-52 might have been broken by communist signals intelligence services of the GDR, Czechoslovakia and Poland.

* Jan Bury, From the Archives: CX-52 Messages Read by Red Poles ?, Cryptologia 33 ( 4 ), October 2009, pp347 – 352.

* Technical details of the C-52 and CX-52 Encryption principle and machine variations, by Dirk Rijmenants

* Jerry Proc's page on the CX-52 — also covers the B-52 keyboard unit.

The CX-52 version has 6 pinwheels with 47 pins each and a flexible wheel movement system.

The C-52 and CX-52 were very flexible machines that could be produced in various ways, creating a unique machine with unique cryptographic characteristics for each customer.
