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.

Beautiful bodies

However, artificial beings need not be invisible or look like Arnold Schwarzenegger in "Terminator". "My dream would be to create an artificial man that does not look like a robot but like a beautiful, graceful human being. The artificial man should be beautiful". Nadia Thalman's hopes for beautiful robots may become reality in the work of MIRALab, a research laboratory attached to the University of Geneva dedicated to realistic modelling of human functionalities. The laboratory has produced an artificial Marylyn Monroe showing just how beautiful artificial creatures can be, and there is a biography featuring details of her career and her - however virtual - love life. Yet beautiful creatures have been made before, at leas on the movie screen. Frank-N-furter, the protagonist of the Rocky Horror picture show ("I've been making a man / with blond hair and a tan / and he is good for relieving my /tension) did set remakrable esthetic standards.

While in Hindu mythology, avatars are bodies chosen by gods for their representation on earth, often animals such as swans or horses, the avatars populating cyberspace have a different function. The cyber bodies of real people, often 3 dimensional images of creatures whose aesthetics reflects both the tastes prevalent in the entertainment and advertising industries as the state of art in visual representation.
