Improved Meet-in-the-Middle Nostradamus Attacks on AES-like Hashing by Xiaoyang Dong, Jian Guo, Shun Li, Phuong Pham, Tianyu Zhang

“…Kelsey and Kohno demonstrated a herding attack requiring O(√n · 22n/3) evaluations of the compression function of H, where n represents the output and state size of the hash, placing this attack between preimage attacks and collision searches in terms of complexity. At ASIACRYPT 2022, Benedikt et al. transform Kelsey and Kohno’s attack into a quantum variant, decreasing the time complexity from O(√n · 22n/3) to O( 3√n · 23n/7). …”

Automatic Preimage Attack Framework on Ascon Using a Linearize-and-Guess Approach by Huina Li, Le He, Shiyao Chen, Jian Guo, Weidong Qiu

“…The preimage attack framework, utilizing the linear structure with the allocating model, was initially proposed by Guo et al. at ASIACRYPT 2016 and subsequently improved by Li et al. at EUROCRYPT 2019, demonstrating high effectiveness in breaking the preimage resistance of Keccak. …”
