A New cryptanalysis model based on random and quantum walks

Abstract

Randomness plays a key role in the design of attacks on cryptographic systems and cyber security algorithms in general. Random walks and quantum walks are powerful tools for mastering random phenomena. In this article, I propose a probabilistic attack model of a cryptographic system. This model is based on a random or quantum walk with the space of states being a space containing the secret to be revealed. This space can be a subspace of keys, plain texts or cipher texts.
