What is a Feistel Network?

A Feistel Network is a cryptographic approach used within the creation of Block Cipher-based Algorithms and mechanisms. Designed with the aid of IBM personnel Horst Feistel and Don Coppersmith, the first use of the Feistel commUnity cHanged into in Lucifer Block Cipher.

A Feistel network is also referred to as a Feistel cipher.

What Does Feistel Network Mean?

A Feistel network implements a series of iterative ciphers on a bLock of facts and is normally designed for block ciphers that encrypt big quantities of facts. A Feistel network works through splitting the Data block into identical pieces and making use of Encryption in multiple rounds. Each spherical implements permutation and combos derived from the primary Characteristic or key. The Range of rounds varies for each cipher that implements a Feistel network.

Moreover, as a reversible algorithm, a Feistel commuNity produces the identical Output till the input is the same.
