Cryptography
Definition
Technique having for goal to quantify a message, i.e. to make it inintelligible to the eyes of those for which it is not intended.
Description
Modern cryptography is based primarily on mathematical and algorithmic concepts. There are two great types of cryptography: systems called to secret key and public key. Whereas in the first case, the safety of the message rests entirely on the secrecy of the key of coding, the second system allows the public diffusion of the key, from where the name. The AES and the RSA are respectively algorithms with secret key and public key.
