Cryptography diffusion
WebMar 14, 2024 · Information Security Safe & Security Data Structure. Diffusion is an encryption process where the authority of one plaintext symbol is spread over some ciphertext symbols with the objective of hiding statistical properties of the plaintext. A simple diffusion element is the bit permutation, which can be used frequently within DES. WebNov 18, 2024 · The DES (Data Encryption Standard) algorithm is a symmetric-key block cipher created in the early 1970s by an IBM team and adopted by the National Institute of Standards and Technology (NIST). The algorithm takes the plain text in 64-bit blocks and converts them into ciphertext using 48-bit keys.

WebAug 31, 2024 · In modern cryptography, "confusion" is often used in a broader sense. For example, one can reasonably talk about confusion even in the absence of a key (e.g. in permutation-based cryptography). That's a different question though. Conclusion I should reiterate that "confusion" and "diffusion" are rather vague.
