WebThey are called Feistel ciphers (also Feistel functions) after Horst Feistel, the inventor of the concept, and the primary inventor of DES. All Feistel ciphers work in the same way: They divide the block into two halves, apply a round function to one of those halves, and then swap the halves. This is done each round.
