WebCryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. [1] Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown. Web2.1.1 Linear Cryptanalysis Linear cryptanalysis exploits approximate linear relationships that exist between inputs and outputs of a function block [1]. In the case of a block cipher, linear combinations of plaintext patterns and linear combinations of ciphertext patterns are compared to linear combinations of key bits.
