some essential definitions some essential definitions in the field of cryptography are: - cryptoanalysis - cryptology - ciphers "Few false ideas have more firmly gripped the minds of so many intelligent men than the one that, if they just tried, they could invent a cipher that no one could break." (David Kahn) codes plaintext ciphertext to encipher/encode to decipher/decode The variants of encryption systems are endless. For deciphering there exists always the same game of trial and error (first guessing the encryption method, then the code). A help to do so is pruning. Once, after a more or less long or short period a code/cipher breaks. Monoalphabetic ciphers can be broken easily and of course are no longer used today but for games. for further information on codes and ciphers etc. see: http://www.optonline.com/comptons/ceo/01004A.html http://www.ridex.co.uk/cryptology/#_Toc439908851

Intellectual property Intellectual property, very generally, relates to the output that result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches: 1) industrial property (inventions, marks, industrial designs, unfair competition and geographical indications), and 2) copyright. The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products.
