Data Encryption Standard (DES) and Core Cipher Concepts
Data Encryption Standard (DES) Algorithm Explained
The Data Encryption Standard (DES) is a symmetric-key block cipher developed in the 1970s by IBM and adopted by the US government. It encrypts data in 64-bit blocks using a 56-bit key.
How DES Works
- Initial Permutation (IP): The 64-bit plaintext goes through an initial permutation, which shuffles the bits according to a fixed table.
- Divide into Halves: The permuted text is split into two 32-bit halves: Left (L0) and Right (R0).
