'''Differential cryptanalysis''' is a general form of [[cryptanalysis]] applicable primarily to [[block cipher]]sciphers, but also to [[stream cipher]]sciphers and [[cryptographic hash function]]sfunctions. In the broadest sense, it is the study of how differences in information input can affect the resultant difference at the output. In the case of a block cipher, it refers to a set of techniques for tracing differences through the network of transformationstransformation, discovering where the [[cipher]] exhibits non-[[randomness|random]] behavior, and exploiting such properties to recover the secret [[key (cryptography)| key]].
