Number the letters of the alphabet starting at 0, so A= 0,B= 1,...,Z= 25. The key space K= {0,...,25}. To encrypt, E kreplaces each letter mby the letter (m+ k) mod 26. To decrypt, D
Webk3 Iterated Ciphers • Plaintext undergoes encryption repeatedly by underlying cipher • Ideally, aach stage uses a different key • In practice triple cipher is usually C= E k1 (E k2 (E k1 (P))) [EEE mode] or C= E k1 (D k2 (E (P))) [EDE mode] EDE is more common in practice Necessary Condition • For some block ciphers iteration does not ... WebTriple DES (or TDES or TDEA or 3DES) is a symmetric block cipher standardized by NIST in SP 800-67 Rev1 , though they will deprecate it soon. TDES has a fixed data block size of 8 bytes. It consists of the cascade of 3 Single DES ciphers (EDE: Encryption - Decryption - Encryption), where each stage uses an independent DES sub-key.
