WebFeistel Block Cipher. Feistel Cipher is not a specific scheme of block cipher. It is a design model from which many different block ciphers are derived. DES is just one example of a Feistel Cipher. A cryptographic system based on Feistel cipher structure uses the same algorithm for both encryption and decryption. WebThe Hill Cipher, created by Lester Hill in 1929, is a cipher that has not been successfully decrypted in a ciphertext only attack [3]. Numerous attempts have been made over the …
