Comprehensive Preimage Security Evaluations on Rijndael-based Hashing

ePrint Report: Comprehensive Preimage Security Evaluations on Rijndael-based Hashing

Tianyu Zhang

The Meet-in-the-Middle (MITM) attack is one of the most powerful cryptanalysis techniques, as seen by its use in preimage attacks on MD4, MD5, Tiger, HAVAL, and Haraka-512 v2 hash functions and key recovery for full-round KTANTAN. An efficient approach to constructing MITM attacks is automation, which refers to modeling MITM characteristics and objectives into constraints and using optimizers to search for the best attack configuration. This work focuses on …
