Diving deep into the preimage security of AES-like hashing by Chen, Shiyao, Guo, Jian, List, Eik, Shi, Danping, Zhang, Tianyu

“…Since the seminal works by Sasaki and Aoki, Meet-in-the-Middle (MITM) attacks are recognized as an effective technique for preimage and collision attacks on hash functions. At Eurocrypt 2021, Bao et al. automated MITM attacks on AES-like hashing and improved upon the best manual result. …”

Towards closing the security gap of Tweak-aNd-Tweak (TNT) by Guo, Chun, Guo, Jian, List, Eik, Song, Ling

“…To address this deficit, Bao et al. proposed Tweak-aNd-Tweak (TNT) at EUROCRYPT’20. Their construction chains three calls to independent keyed permutations and adds the unmodified tweak to the state in between the calls. …”
