Network Security - DES (Data Encryption Standard) Algorithm

Explore the Data Encryption Standard (DES) algorithm in this 50-minute video lecture on network security. Dive into the Feistel Structure, which forms the basis of DES and many other block cipher algorithms. Learn about the key components of DES, including its 64-bit block size, 16 rounds of encryption, 64-bit key size, and 48-bit sub-keys. Understand how the algorithm processes plaintext to produce 64-bit ciphertext. Gain valuable insights into this fundamental encryption method, essential for anyone studying or working in network security and cryptography.
