Web線形解読法(せんけいかいどくほう、英語: Linear cryptanalysis)とは、暗号化変換の線形近似式を発見することを基本とした一般化された暗号解読手法の一つである。 この攻撃は、ブロック暗号およびストリーム暗号に適用される。 線形解読法は、ブロック暗号にもっとも適用される攻撃法の二つのうちの一つである(もうひとつは、差分解読法であ … Differential cryptanalysis is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions. 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 transformation, discovering where the cipher exhibits non-random behavior, and exploiting such …

WebStream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor is performed bit by bit.
