Understanding DES Round Structure in Cryptography 🔐

Join us as we break down the DES encryption process into rounds, each contributing to the robust security of this historic cryptographic algorithm. From the initial permutation to the final output, we dissect each step, shedding light on the complexity and strength that DES brings to data protection.

🔍 Key Highlights:
1️⃣ Introduction to DES Rounds: A brief overview of the importance of rounds in the DES encryption process.
2️⃣ Initial Permutation: Understanding how the input data is permuted at the beginning of each round.
3️⃣ Feistel Network: Exploring the Feistel structure that forms the foundation of DES rounds.
4️⃣ Key Generation: Insight into the generation and usage of subkeys for each round.
5️⃣ Expansion and Permutation: Breaking down the expansion and permutation steps crucial to DES encryption.
6️⃣ Substitution and Permutation: Examining the S-boxes and the final permutation in the DES round structure.
