Computer Cryptology

Cryptology involves both the fields of cryptography and cryptanalysis. Computer cryptology is aslo known as bitstream cryptology. The operations of all the algorithms in computer cryptology or bitstream cryptology are based on the basic unit of bit streams for binary bits of bit zero "0" and bit one "1".

For human-based cryptology, it is one symbol many meanings; whereas it is one symbol one meaning for computer cryptology. Hence, there is no one-way function in computer cryptology, which is based on mathematical manipulation of bit streams.

On the other hand, the polysemy features of human-based cryptology has caused the unbreakable situation by any cryptanalytical techniques for the messages encrypted and/or encoded under the human-based cryptology. For instance, visual cryptography is one of the examples of human-based cryptology. This is the major difference of machine language and human language.
