Cryptography diffusion
In cryptography, the avalanche effect is the desirable property of cryptographic algorithms, typically block ciphers and cryptographic hash functions, wherein if an input is changed slightly (for example, flipping a single bit), the output changes significantly (e.g., half the output bits flip). In the case of high-quality block ciphers, such a small change in either the key or the plaintext should caus… In 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 . These properties, when present, work to thwart the application of statistics and other methods of … See more Confusion Confusion means that each binary digit (bit) of the ciphertext should depend on several parts of the key, obscuring the connections between the two. The property of … See more Designing an encryption method uses both of the principles of confusion and diffusion. Confusion means that the process drastically changes data from the input to the output, for example, by translating the data through a non-linear table created from … See more In Shannon's original definitions, confusion refers to making the relationship between the ciphertext and the symmetric key as complex and involved as possible; diffusion refers to dissipating the statistical structure of plaintext over the bulk of See more • Algorithmic information theory • Avalanche effect • Substitution–permutation network See more

WebSep 2, 2024 · In 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. These properties, when present, work to thwart the application of statistics and other methods of cryptanalysis. WebDiffusion is the principle that the plain text and the ciphertext should be structurally independent from the perspective of a statistical analysis; in other words, a change in one small part of the plain text should result in many changes in the ciphertext so that changes in the ciphertext do not reveal information as to the structure of the ...
