In cryptography, the avalanche effect is the desirable property of cryptographic algorithms, typically block ciphers [1] 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 cryptography, confusion and diffusion are two properties 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 .
As of 2008, the best analytical attack is linear cryptanalysis, which requires 2 43 known plaintexts and has a time complexity of 2 39–43 (Junod, 2001). The Data Encryption Standard ( DES / ˌ d iː ˌ iː ˈ ɛ s , d ɛ z / ) is a symmetric-key algorithm for the encryption of digital data.
