This thesis studies the cryptanalysis and design of some cryptographic algorithms in symmetric key ciphers. Block ciphers and Stream ciphers are two backbone elements in symmetric key ciphers. We cryptanalyze ZUC stream cipher, SERPENT, KASUMI and SMS4 block ciphers by using some new improved crypt...
