Routers play a pivotal role in forwarding data packets between different networks within the Transmission Control Protocol/Internet Protocol (TCP/IP) model. The TCP/IP model is a conceptual framework used for understanding how data is transmitted over a network. It consists of four layers: the Application layer, Transport layer, Internet layer, and Network Access layer. The Internet

The Data Encryption Standard (DES) is a symmetric block cipher cryptosystem widely used in the field of classical cryptography. One of the key components of the DES encryption process is the Initial Permutation (IP). The purpose of the IP is to provide a preliminary rearrangement of the input data before further processing. This rearrangement is
