In cryptography , a Feistel cipher is a symmetric structure used in the construction of block ciphers , named after the German-born physicist and cryptographer Horst Feistel who did pioneering research while working for IBM -LRB- USA -RRB- ; it is also commonly known as a Feistel network .
Decryption of a ciphertext -LRB- R_n , L_n -RRB- is accomplished by computing for i = n,n-1 , ldots ,1
