Simplified Meet-in-the-middle Preimage Attacks on AES-based Hashing

2026 · IACR Communications in Cryptology

The meet-in-the-middle (MITM) attack is a powerful cryptanalytic technique leveraging time-memory tradeoffs to break cryptographic primitives. Initially introduced for block cipher cryptanalysis, it has since been extended to hash functions, particularly preimage attacks on AES-based …
