1989 – Quantum cryptography experimentally demonstrated in a proof-of-the-principle experiment by Charles Bennett et al. 1991 – Phil Zimmermann releases the public key encryption program PGP along with its source code, which quickly appears on the Internet. 1994 – Bruce Schneier's Applied Cryptography is published.
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία-logia, "study", respectively [1]), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
The Codebreakers – The Story of Secret Writing (ISBN 0-684-83130-9) is a book by David Kahn, published in 1967, comprehensively chronicling the history of cryptography from ancient Egypt to the time of its writing. The United States government attempted to have the book altered before publication, and it succeeded in part.
Al-Khalil ibn Ahmad al-Farahidi: wrote a (now lost) book on cryptography titled the "Book of Cryptographic Messages". Al-Kindi, 9th century Arabic polymath and originator of frequency analysis. Athanasius Kircher, attempts to decipher crypted messages; Augustus the Younger, Duke of Brunswick-Lüneburg, wrote a standard book on cryptography
In cryptography, a classical cipher is a type of cipher that was used historically but for the most part, has fallen into disuse. In contrast to modern cryptographic algorithms, most classical ciphers can be practically computed and solved by hand.
The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography is a book by Simon Singh, published in 1999 by Fourth Estate and Doubleday. The Code Book describes some illustrative highlights in the history of cryptography, drawn from both of its principal branches, codes and ciphers.
Stonehenge located in Wiltshire, United Kingdom, is one of the world's best known megalithic structures.. Archaeocryptography (from Greek ἀρχαῖος, arkhaios, "ancient" and κρυπτός (kruptós), "hidden, secret"; and γράφειν (graphein), "to write") is the attempt to decode an ancient monument or structure by supposing an underlying mathematical order beneath the proportions ...
