Reliability of Cryptographic Algorithms for Ensuring Information Security in the Context of the Quantum Threat

This paper assesses cryptographic security for new, Fourth Industrial Revolution technologies against quantumenabled risks. In this context, the history of successful attacks on post-quantum cryptography algorithms is reviewed and a thorough cryptographic study of these algorithms' resistance to various cryptographic analysis methods is proposed. The paper also describes an effective attack on a post-quantum algorithm proposed by the authors in earlier studies. This description concludes that using the previously proposed parameters is insecure. Modifying these parameters necessitates further investigation into the cryptographic strength of the post-quantum algorithm.
