Cryptanalysis of AES: Yoyo and Boomerang Attacks (C Implementation)

Description:

This project provides C-based implementations of cryptanalytic attacks on the Advanced Encryption Standard (AES), focusing on two methods: the Yoyo attack and the Boomerang attack. These techniques exploit weaknesses in reduced-round AES to recover secret keys and distinguish AES from random permutations.

---

Features:

• Yoyo Attack on 3- to 5-round AES: Implements key-independent distinguishers and key-recovery attacks with low computational complexity.
• Boomerang Attack on 6-round AES: Combines two short high-probability differentials into an effective distinguisher.

---

Prerequisites:

• C compiler (e.g., GCC)
• Basic understanding of AES encryption
• Familiarity with cryptographic attacks
