   Data Encryption Standard (DES) is a block cipher with a 56-bit key length that has played a significant role in data security. Data encryption standard (DES) has been found vulnerable to very powerful attacks therefore, the popularity of DES has been found slightly on the decline. DES is a block cipher and encrypts data in blocks of size of 64 bits...

   As we have noted, the initial permutation (IP) happens only once and it happens before the first round. It suggests how the transposition in IP should proceed, as shown in the figure. For example, it says that the IP replaces the first bit of the original plain text block with the 58th bit of the original plain text, the second bit with the 50th bi...

   In conclusion, the Data Encryption Standard (DES) is a block cipherwith a 56-bit key length that has played a significant role in data security. However, due to vulnerabilities, its popularity has declined. DES operates through a series of rounds involving key transformation, expansion permutation, and substitution, ultimately producing ciphertext ...
