WebLinear cryptanalysis is a known plaintext attack where the cryptanalyst finds large amounts of plaintext/ciphertext pairs created with the same key. The pairs are studied to derive information about the key used to create them. Both differential and linear analysis can be combined as differential linear analysis. WebIn 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.
