(PDF) Cryptanalysis of Stream Cipher: Method Implementation

WebA stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. WebMay 1, 2024 · In 2002, Krause proposed theoretical framework for BDD-based cryptanalysis of stream ciphers. Since then not much work have been reported in this area.
