Web4 Steganography - Definition XSteganography – from the Greek word steganos meaning “covered” – and the Greek word graphie meaning “writing” XSteganography is the process of hiding of a secret message within an ordinary message and extracting it at its destination XAnyone else viewing the message will fail to know it contains hidden/encrypted data WebIn cryptography, confusion and diffusion are two properties of the operation of a secure cipher identified by Claude Shannon in his 1945 classified report A Mathematical Theory of Cryptography [1]. These properties, when present, work together to thwart the application of statistics and other methods of cryptanalysis.

Compare cryptography. Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown.
