Cryptographic diffusion
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 WebNov 18, 2024 · Diffusion Diffusion can be quantified by examining the branch number of the diffusion layer. The branch number indicates how much a difference in the input will spread around the rest of the state after the transformation has been applied. The branch number can be used to prove lower bounds on the amount of diffusion that the permutation …
