Can single bit of ciphertext be influenced by many bit of plaintext in DES?

Saturday, 10 August 2024 by Emmanuel Udofia

The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of digital data. Developed in the early 1970s and adopted as a federal standard in 1977, DES has been widely used in various applications. One of the critical aspects of DES and other block ciphers is how plaintext bits influence the resulting ciphertext.

The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of digital data. It was developed in the early 1970s and was later adopted as a federal standard in the United States in 1977. DES is a block cipher, meaning it encrypts data in fixed-size blocks, specifically 64-bit blocks, using a 56-bit key.
