Hash function based on controlled alternate quantum walks with memory
Qing Zhou, Songfeng Lu
We propose a new hash function QHFM based on controlled alternate quantum walks with memory on cycles, where the jth message bit decides whether to run quantum walk with one-step m…

Quantum Differential Cryptanalysis
Qing Zhou, Songfeng Lu, Zhigang Zhang +1
In this paper, we propose a quantum version of the differential cryptanalysis which offers a quadratic speedup over the existing classical one and show the quantum circuit implemen…
