Cryptanalysis steganography
WebCryptanalysis: An Overview . Cryptanalysis is the technique of examining cryptographic systems for flaws or information leakage. Cryptanalysis is commonly thought of as searching for flaws in a cryptographic system's core mathematics, but it also involves looking for flaws in implementation, such as side-channel attacks or weak entropy inputs. Whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent and its contents. Steganography includes the concealment of information within computer files. See more Steganography is the practice of representing information within another message or physical object, in such a manner that the presence of the information is not evident to human inspection. In … See more Discussions of steganography generally use terminology analogous to and consistent with conventional radio and communications technology.
