摘要

Feistel ciphers are named after Horst Feistel who studied these schemes in the 1960s. In this chapter, we will only present classical Feistel ciphers, i.e., balanced Feistel ciphers with the \(\oplus \) group law (Xor). In Chaps.  8 , 9 , and 10 , we will see that there are many variants of these ciphers.
