What is the Feistel network structure and how does it relate to DES?
Thursday, 03 August 2023 by EITCA Academy
The Feistel network structure is a symmetric encryption scheme that forms the basis for the Data Encryption Standard (DES), a widely used block cipher cryptosystem in classical cryptography. The Feistel network structure was introduced by Horst Feistel in the early 1970s and has since been adopted in various encryption algorithms due to its simplicity and
