Symmetric-key cryptosystems use the (71 ) key for encryption and decryption of a message,though a message or group of messages may have a different key than others. A significant disadvantage of symmetric ciphers is the key management necessary to use them securely. Each distinct pair of communicating parl ies must, ideally, share a different key, and perhaps each ciphertext exchanged as well. The..

The modern study of symmetric-key ciphers relates mainly to the study of block ciphers and stream ciphers and to their applications. A block cipher is, in a sense, a modern embodiment of Alberti's polyalphabetic cipher: block ciphers take as input a block of （71）and a key, and output a block of ciphertext of the same size. Since messages are almost always longer than a single block, some method ..
